Babies' first words are often seen as a important and precious moment in their development, marking the beginning of their journey into verbal communication. For instance, when the baby looks at his or her parent and says "mama" for the first time, it brightens up the parent's face with joy but it is a meaningful connection in their bond that is growing. For parents, these are some sources of pride and joy. But how do you determine whether your child's speech and language are progressing?

Understanding the communication milestones will help monitor a child's development and spot potential issues before they become more serious. The milestones serve as benchmarks to guide health care providers on whether a child needs further assistance.

Importance of Communication Development in Early Years

The first five years of a child's life are the time of massive growth and brain development at an incredible speed. All domains of development find their roots within this period, including communication. From the day they were born, babies start crying to communicate, and within weeks or months, they begin to babble, imitate sounds, and eventually words. Communication is not only important to express needs but also for understanding the world and building relationships. It is an important tool that supports cognitive, emotional, and social development.

Speech Milestones by Age

Babies learn communication skills at their own pace. General milestones can, however serve as a guideline for typical development. Let's go through these milestones by age:

Newborn (0-3 Months)

At this point, the babies communicate mostly through crying. They give cues as to their needs by responding with actions like smacking the lips when hungry or arching the back when they feel overstimulated. At the end of three months, you may also observe:

• Smiles in response to your appearance.
• Cooing sounds.
• Quiets or smiles when spoken to.
• Your voice.
• Different cries for specific needs.

Upto 6 Months

By six months, babies start experimenting with sounds and use their voice to play. Major developments include:

• Making gurgling sounds during play.
• Babbling with different sounds.
• Vocalizing likes and dislikes.
• Responding to the change in tone of voice.
• Turning eyes toward sounds.
• Showing interest in music and sound-making toys.

Till 12 Months

By the first birthday, there are some significant communication milestones that have been achieved:

• Trying to imitate speech sounds.
• Speaking basic words like "mama," "dada," or "uh-oh."
• Responding to simple commands, such as "Come here."
• Recognizing common items by name, like "shoe."
• Turning toward sounds and voices.

Upto 18 Months

In this stage, children learn to understand and use words in a consistent manner. Some of the important milestones are:

• Knows the names of people, objects, and body parts.
• Responds to simple commands with gestures.
• The child says up to 10 words.

End of 24 Months

By two years of age, children usually have more developed communication skills:

• Using simple sentences, like "more milk."
• Asking one- to two-word questions, such as "Go bye-bye?"
• Following simple directions and answering simple questions.
• Saying 50 or more words.
• Being understood by family members at least half the time.

Ways Parents Can Support Development

Parents can be very supportive in developing the communication skills of their child. Here are some effective strategies:

1. Pay Attention to Hearing: Ensure your child responds to sounds and voices. Notice if they react to noise or look at you when spoken to. If you suspect hearing issues, consult your pediatrician promptly.

2. Engage in Conversation: Respond to your baby’s coos and babbles. Talk to them frequently about daily activities, like “Mommy is making breakfast,” or “We’re going to the park.”

3. Imitation Training: Teach your baby to imitate actions and gestures of others, such as clapping, waving, or peek-a-boo. These activities encourage her to understand turn-taking and even nonverbal communication.

4. Animals Sound: Learning time must be fun. Train your baby to imitate an animal's sound, "A cow says 'moo.'". This encourages sound production along with word association.

5. Read and Sing Together: Reading stories and singing songs expose your child to language patterns and rhythm. Make it a daily habit to promote vocabulary growth.

6. Use Your Native Language: Speak to your child in the language you’re most comfortable with. Early exposure to rich language environments helps babies learn effectively.

7. Strengthen Their Attempts: Cheer every time your child tries to speak. Repeat the words and sounds and gently correct as needed. A little "baby talk" is okay but clearly say simple words for them to imitate.

When to Seek Medical Attention

Though every child develops at his own rate, there are some delays that point toward professional intervention. Talk with your child's health care provider if:

- Doesn't turn toward sounds or his name.

- By 12 months, he isn't babbling, and by 18 months, he has not spoken a single word.

- Uses speech in a peculiar manner or shows delayed speech.

Your pediatrician can refer you to some specialist who could be an audiologist or speech-language pathologist for more extensive testing. In the case of a bilingual child, he will also be evaluated by a bilingual speech-language pathologist.

Communication milestones form a kind of roadmap in understanding how your baby develops. This means through conversation, play, and learning activities, you could be able to enhance language skills while promoting your child's development. When concerned about delay, consult professional help, as this might make all the difference by having communication skills set up to meet a great future for your child.

Communication Milestones: Birth to 1 Year. American Speech-Language-Hearing Association

The pertussis vaccine, which protects against whooping cough (Bordetella pertussis), a highly contagious bacterial respiratory infection, offers strong protection in young children, according to a new study led by the US Centers for Disease Control and Prevention (CDC).

Published in the CDC’s Morbidity and Mortality Weekly Report (MMWR), the study found that children who received three or more doses of the diphtheria, tetanus, and acellular pertussis (DTaP) vaccine had 96.2% protection against laboratory-confirmed pertussis.

Pertussis Vaccine Offers Strong Protection

The DTaP vaccine is administered in a five-dose childhood series. The first dose is given at 2 months of age, followed by doses during infancy and early childhood. The final dose is recommended between ages 4 and 6 years.

The MMWR study compared children in Alaska who had received three or more DTaP doses with those who were unvaccinated or had received fewer doses than recommended.

Unvaccinated children had approximately 26 times the odds of developing laboratory-confirmed whooping cough compared with vaccinated children.

Overall, adjusted vaccine effectiveness against pertussis was 96.2% among children who had received three or more DTaP doses. Partial vaccination also offered protection, with effectiveness reaching 85.3% among children who had received one or two doses.

“Pertussis vaccination is effective in preventing laboratory-confirmed pertussis in young children,” said corresponding author Joseph McLaughlin of the Section of Epidemiology, Alaska Department of Health, Anchorage.

Whooping Cough Can Cause Severe Complications

Pertussis can cause serious complications in young children, including pneumonia, pauses in breathing (apnea), seizures, brain damage, and death. Severe coughing fits can also trigger vomiting and, in some cases, fractured ribs.

Infants younger than 6 months are particularly vulnerable because their immune systems are still developing. Babies may not develop the characteristic “whoop” sound and can instead experience feeding difficulties or pauses in breathing, making the infection harder to recognize.

According to a provisional CDC report, 16 people died from pertussis in the United States in 2025, including 10 infants.

Whooping cough spreads through respiratory droplets and can affect people of any age. However, newborns and people who are not adequately vaccinated face a greater risk of severe illness.

Previous research has also found that unvaccinated children are more likely to develop severe illness or require hospitalization than vaccinated children.

Childhood Vaccination Rates Have Declined In The US

Despite the protection offered by vaccination, DTaP coverage among US kindergartners has declined in recent years.

CDC data show that coverage fell to 92% in the 2025–26 school year, down from 95.2% in 2017–18.

The findings underscore the importance of maintaining high childhood vaccination coverage to reduce pertussis infections and protect children against severe illness and death.

Identifying Whooping Cough Symptoms

Whooping cough often begins with cold-like symptoms, including a runny nose, sneezing, a mild cough, and sometimes a low-grade fever. After one to two weeks, coughing fits may become more severe and persistent.

The cough can be followed by a characteristic whooping sound as the person gasps for air. Vomiting after coughing fits can also occur. However, symptoms vary, particularly in infants, who may experience breathing difficulties without a typical cough.

Diagnosis may involve laboratory testing of a nasal or throat sample. Early recognition is especially important in infants because the infection can progress to serious complications.

Herpes simplex virus (HSV), which commonly causes cold sores, usually causes mild symptoms in adults but can be life-threatening in newborns, whose immune systems are still developing.

Meg Edmonds, from Staffordshire, UK, lost her 10-day-old daughter, Magnolia, to HSV in February.

“We didn't know a cold sore could kill a baby,” Meg told the BBC. She is now urging parents to learn about the risks cold sores pose to newborns.

The virus is suspected to have been passed on to Magnolia by her mother.

“The guilt is obviously unbearable; it's horrific, but I just try and remind myself that I didn't know and I did what I could have done with the knowledge that I did have,” Meg said.

The 22-year-old said Magnolia was born “perfectly healthy” after what she described as a straightforward “water birth”.

Only later did Meg realise she had a sore on her lip around the time of the birth.

“Looking back at photos now, I can see that I had a lesion or sore on my lip whilst I was giving birth which I thought nothing of at the time,” she said.

Meg, who had never experienced a cold sore before, sought advice from health professionals but was reassured that the sore was nothing to worry about.

“They just thought that I might need to drink more or that it might just have been hormonal from giving birth only the day prior, so I thought nothing of it,” she said.

Magnolia's condition later deteriorated, and she died from HSV, according to the report.

Cold Sore Outbreak Brings Back Painful Memories

Meg said she had avoided visitors who were unwell, never kissed Magnolia and washed her hands frequently to protect her newborn from infections.

“I washed my hands constantly because I was worried in general about infections. But I never knew that if that passed to her it could kill her,” she said.

A subsequent cold sore outbreak brought back painful memories.

“I'm constantly reminded anyway that my daughter isn't here any more and why that is, but to actually have a physical reminder on my face is horrible,” she said.

How To Protect Newborns From HSV

According to the UK's National Health Service (NHS), newborns are particularly vulnerable to HSV, especially during the first six weeks of life. The infection can affect the eyes, mouth and skin or spread to other organs, potentially becoming life-threatening.

HSV can spread after birth through contact with a cold sore, including when someone with an active cold sore kisses a baby. It can also spread through herpes blisters on the breast during breastfeeding.

The NHS recommends these precautions to reduce the risk of infection:

• Wash hands: Wash hands thoroughly before handling a newborn.
• Avoid kissing: People with an active cold sore should not kiss a baby.
• Prevent direct contact: Keep cold sores and other herpes lesions away from the baby.
• Take care during breastfeeding: Do not breastfeed from a breast with herpes blisters until they have healed. Seek medical advice about feeding and expressed milk from the affected breast.
• Inform healthcare professionals: Pregnant women with a history of genital herpes or symptoms of a possible infection should inform their doctor or midwife.

Warning Signs Of Neonatal Herpes

Babies may not develop visible blisters, and neonatal herpes can progress rapidly. Seek urgent medical attention if a newborn has:

• Unusual irritability or difficulty settling.
• Poor feeding or feeds less than usual.
• A fever of 38°C or higher.
• A rash or sores on the skin, eyes or inside the mouth.
• Unusual lethargy, floppiness or difficulty waking.
• Breathing difficulties or seizures.

Influenza and COVID-19 may trigger a rare but fatal brain condition in children, according to a new study published in Frontiers in Neurology.

Based on 138 reported cases of acute necrotizing encephalopathy (ANE), the research is built on 15 studies involving children under 18 diagnosed with ANE following respiratory viral infections.

ANE can cause rapid neurological deterioration, seizures and damage to deep structures of the brain, even in children who were previously healthy.

Influenza viruses accounted for 46% of the reported cases, while SARS-CoV-2, the COVID-19 virus, accounted for 42.3%. Together, they represented nearly 90% of the cases in the review.

The findings highlight the need to recognise neurological symptoms that develop after a child has a fever or respiratory infection.

However, ANE remains rare, and the study does not suggest that most children with flu or COVID-19 are at risk of developing the condition.

Flu And COVID-19 Accounted For Most Reported Cases

Influenza viruses were identified in 63 cases, while SARS-CoV-2 was identified in 58. Another 17 cases were linked to unspecified respiratory viral infections.

The findings suggest that influenza and COVID-19 are key reported triggers of ANE. However, the researchers cautioned that the studies were observations, and the findings cannot establish how often ANE develops among children infected with either virus.

What Is Acute Necrotizing Encephalopathy?

Acute necrotizing encephalopathy is a rare neurological disorder in which inflammation and tissue injury cause damage to the brain. It is mostly linked with a respiratory viral infection.

The condition is characterised by lesions in the thalami, two structures deep inside the brain that help process sensory information and regulate functions like alertness.

In some children, damage also affects the brainstem and other regions. Rather than the virus directly destroying brain tissue, an excessive inflammatory response may disrupt the blood-brain barrier, allowing inflammation to damage the brain.

Symptoms of Acute Necrotizing Encephalopathy

ANE usually starts with symptoms of the initial viral infection, like fever, cough, vomiting, and diarrhea, followed by rapid neurological decline, which may include:

• Seizures
• Confusion, drowsiness, and altered consciousness
• Coma lasting for weeks
• Problems with movement (ataxia)
• Abnormal muscle tone

One of the most concerning features of ANE is how quickly a child's condition can worsen after a febrile illness.

In the reviewed cases, fever was reported in 93.4% of children, altered consciousness in 94.9% and seizures in 68.6%. These figures describe children who had ANE, not all children with respiratory infections.

These symptoms require emergency medical assessment. Parents should not wait for a fever or other infection symptoms to resolve if a child develops seizures, confusion or reduced consciousness.

Mortality Rate Of ANE

Despite treatment, the outcomes reported in the study were serious. Of the 138 children included in the review, 54 died, giving a reported mortality proportion of 39.1%.

Survivors also experienced neurological complications, including problems affecting movement, cognition and development.

It is important to note that the study included published cases of a rare and severe disease, which may overrepresent children with particularly serious illness. It is not a population-wide estimate of the risk of death from ANE. Brain imaging like MRI can help doctors identify the characteristic lesions associated with the condition.
