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.

Rare infections transmitted from a pregnant woman to her baby may be linked to a higher risk of autism and intellectual disability, according to a large new study.

Researchers at the Karolinska Institutet in Sweden found that children with congenital TORCH infections had about three times the risk of autism compared with children without these infections.

What Is TORCH?

TORCH refers to infections that can be transmitted from mother to foetus during pregnancy, including:

• T = Toxoplasma
• O = Other (including infections such as syphilis):
• R = Rubella
• C = Cytomegalovirus (CMV)
• H = Herpes simplex virus

These infections can cross the placenta and infect the developing fetus.

“It is important to emphasize that it is unusual for these infections to be transmitted from mother to child. They account for a very small proportion of all cases of autism in the population, but for those children who are actually affected, we see a clearly elevated risk of both autism and intellectual disability,” said Reneé Gardner, a researcher at the Department of Global Public Health at Karolinska Institutet.

TORCH Infections And Autism Risk

Published in JAMA Pediatrics, the study analysed data from 3.7 million people born in Sweden between 1987 and 2021. Of these, 975 had a diagnosed congenital TORCH infection. The participants were followed for up to three decades.

Compared with children without a congenital TORCH infection, those with one were:

• About three times more likely to be diagnosed with autism
• More than seven times more likely to have an intellectual disability
• Up to 30 times more likely to have severe to profound intellectual disability

What Did The Sibling Comparison Show?

The researchers also compared children with TORCH infections with their unaffected siblings to assess whether shared family factors could explain the findings.

The results were similar, suggesting that the associations were not explained solely by factors shared within families.

No clear association was found between TORCH infections and ADHD or obsessive-compulsive disorder. However, children with the infections had poorer academic performance on average, even when they did not have an autism or intellectual disability diagnosis.

Can TORCH Infections Be Prevented?

“Although these congenital infections are rare, some of them can be prevented, which makes them important from a public health perspective,” Gardner said.

The researchers also noted that rubella has virtually disappeared in Sweden following the introduction of national vaccination program. The prevention also depends on the infection:

• Toxoplasmosis: Avoid raw or undercooked meat, wash produce and take precautions when handling cat feces.
• Syphilis and other infections: Pregnancy screening and appropriate treatment can reduce transmission.
• Rubella: MMR vaccination before pregnancy can prevent infection.
• CMV: Good hand hygiene and avoiding contact with young children's saliva and urine can reduce exposure.
• Herpes simplex: Identifying and managing genital herpes during pregnancy can reduce the risk of transmission to the newborn. Caesarean delivery may be recommended in some cases when active lesions are present during labor.

We may now have a clearer explanation behind ‘mommy brain’ or ‘momnesia’. Walking into a room and forgetting why you went there or losing track of a conversation is not simply a side effect of becoming a mother.

A new study has discerned a possible explanation for the phenomenon commonly known as “momnesia,” “pregnancy brain” or “mommy brain”. The findings were published in Science Bulletin.

According to the study, persistent high levels of estrogen during pregnancy may disrupt a particular brain circuit involved in memory.

Researchers found that high estrogen affected communication between the hypothalamus and hippocampus, two brain regions involved in regulating different aspects of brain function, including memory.

What Is “Momnesia”?

Pregnancy-related forgetfulness is generally considered to be temporary changes in memory and cognition during pregnancy.

Researchers say forgetfulness can become noticeable in late pregnancy stage and may continue well into the postpartum period before improving.

Women may have trouble recalling names or words, keeping track of events or completing everyday tasks.

According to the author of the study Dr Zheng Sun of Baylor College of Medicine, about 80% of pregnant women report these changes. The researchers say that this condition does not appear to be a decline in intelligence or cognitive ability.

According to Reuters, Dr Yanlin He, another study leader, said, “The important point is that pregnancy does not simply make someone ‘less intelligent.’ The effects appear to be more subtle and specific to certain cognitive tasks.”

Link Between Pregnancy Hormones And Memory

During pregnancy, estrogen levels increase drastically and reach its peak during the third trimester.

The researchers focused on estrogen receptor alpha in neurons located in the lateral hypothalamus. In experiments based on mice who were exposed to high estrogen level conditions like in pregnancy, these neurons became more active.

Those neurons send signals to the hippocampus, a brain region crucial for memory formation. The researchers found that increased activity in this region suppressed hippocampal activity and impaired performance on memory tests.

When researchers switched off the hypothalamus-to-hippocampus pathway, the memory problems in the mice were prevented. Activating the pathway, meanwhile, impaired memory even without elevated estrogen.

Removing estrogen receptors from the hypothalamic neurons also reversed the estrogen-related memory problems in the mice.

Does Pregnancy Actually Make You Forgetful?

The researchers also assessed memory in 70 women, including women at different stages of pregnancy and women who were not pregnant.

Memory problems surfaced during late pregnancy stages and were linked with higher circulating estrogen levels. The researchers reported changes across several memory-related tasks.

But it is important to note that the researchers did not directly measure or manipulate this specific brain circuit in pregnant women. That means the human findings support the mechanism observed in mice, but do not prove that exactly the same circuit causes memory changes during human pregnancy.

The study has cemented evidence that many pregnant women experience forgetfulness, but it does not mean pregnancy causes permanent memory loss. For most women, pregnancy-related forgetfulness generally improves after childbirth.

The gut microbiome may influence how type 1 diabetes develops in children at high genetic risk, a new study suggests.

Researchers found that children whose gut microbiome stopped developing early had about three times the risk of developing type 1 diabetes or the immune attack that precedes it, compared with those whose microbiomes continued to mature.

The findings, published in Nature Metabolism, also showed that genetics influenced how strongly some microbiome patterns were associated with disease risk.

Type 1 diabetes affects more than 9 million people worldwide, including 1.8 million children and adolescents.

"Understanding the role of microbiome development in diabetes progression could lead to early prediction and prevention strategies, giving us more options to delay or even prevent the clinical manifestation of this disease," said co-corresponding author Daniel Wang, associate scientist with the Channing Division of Network Medicine in the Mass General Brigham Department of Medicine.

The longitudinal observational TEDDY Study followed 887 children at high genetic risk of type 1 diabetes and analyzed more than 12,000 stool samples collected during their first six years.

Participants came from Finland, Germany, Sweden and the United States.

Because the immune system can attack insulin-producing cells years before symptoms appear, researchers counted both the first detection of this immune attack and a clinical diagnosis as disease-related outcomes.

They identified three microbiome development patterns: early-matured, late-matured and early-plateaued.

Children with early-matured microbiomes developed greater bacterial diversity during their first year. Those with late-matured microbiomes started more slowly but eventually caught up.

The early-plateaued group showed slow development that failed to catch up, with low bacterial diversity persisting through the first three years.

Early Plateau Linked To Higher Risk

Children with an early-plateaued microbiome had about three times the risk of developing type 1 diabetes or its preceding immune attack.

The association was also seen when the researchers analyzed the immune stage and clinical diagnosis separately.

The finding emerged from repeated stool sampling over time, suggesting a single microbiome snapshot could have missed the association.

Microbiome Reflected Dietary Changes

The bacterial differences also reflected how the children's microbiomes adapted as their diets changed.

In the early-matured group, bacteria shifted sooner from milk-adapted species such as Bifidobacterium toward bacteria that break down dietary fiber.

In the early-plateaued group, the microbiome remained more focused on digesting milk sugars even after solid foods were introduced and relied on a narrower range of bacterial species.

Genetics Also Played a Role

Lead author Danyue Dong, a postdoctoral research fellow in the Channing Division of Network Medicine at Mass General Brigham shared that "genetic background" can also influence the risk. Dong noted that combining microbiome and genetic information gives a more accurate picture.

"By analyzing interactions between the microbiome and host genetics, we found genetic variants, particularly those involved in antimicrobial and antiviral immune responses, that shaped how strongly the late-matured pattern was related to disease risk. The early-plateaued pattern, by contrast, carried higher risk regardless of genetic background," the expert said.

What It Means for Prevention

The study was observational, so it cannot establish that microbiome changes cause type 1 diabetes. Clinical trials are needed to determine whether modifying the microbiome can reduce disease risk.

The findings also came from children already at high genetic risk, meaning they may not apply to the general population.

Researchers say future pediatric care could potentially include microbiome testing during the first years of life. However, approaches such as dietary supplements would need to prove effective in clinical trials before being used for prevention.
