Your baby’s brain grows at an astonishing pace: by the seventh week of pregnancy, new brain cells are being created at roughly 250,000 neurons per minute! While much of brain development is guided by genetics, research shows that a parent’s lifestyle and environment can help boost healthy brain growth. Here are evidence-backed habits that can nurture your baby’s brain development even before birth.
One of the best gifts you can give your baby’s brain is to get moving (with your doctor’s OK, of course!). Moderate exercise during pregnancy increases blood flow and oxygen to both you and your baby, creating a healthier environment for the developing brain. In fact, studies have found that moms who stay physically active tend to have babies with more advanced brain development. For example, higher maternal activity levels are associated with greater newborn cortical brain thickness, which suggests better brain maturation. Another study found that just 20 minutes of moderate exercise (like brisk walking) three times a week led to newborns with more mature brain function on EEG scans.
The benefits of prenatal exercise are so clear that experts encourage it for most healthy pregnancies. The CDC recommends aiming for 150 minutes of moderate exercise per week (e.g. 30 minutes, 5 days a week) during pregnancy. A few safe options include brisk walking, prenatal yoga, swimming, or stationary cycling.
Finding ways to reduce stress is more than just self-care, it’s baby brain care! High levels of maternal stress hormones (like cortisol) can cross the placenta and affect the developing fetal brain. A growing body of research using prenatal MRI has shown that when an expectant mother is very stressed, anxious, or depressed, the baby’s brain may develop differently. For instance, one study found that maternal stress (even short of a diagnosed disorder) was linked to babies having a smaller hippocampus (a brain region important for memory) and other structural changes. And by 18 months of age, infants who were exposed to higher prenatal stress scored lower on cognitive development tests.
The good news is that managing your stress can help buffer your baby! In one University of California San Francisco study, pregnant women under high stress took an 8-week mindfulness meditation class. The results were remarkable: Their infants at 6 months old showed healthier stress responses (calming themselves more quickly and “bouncing back” faster after a stressor) than infants whose moms didn’t get the mindfulness training. In other words, a calmer pregnancy can lead to a calmer, more resilient baby. Experts call this a “two-generation” effect, as helping moms cope with stress benefits children too.
Here are some stress-busting habits to practice during pregnancy:
By the middle of pregnancy, your baby’s ears are developed enough to hear sounds outside the womb. Researchers have found fetuses respond to voices and noise by around 25 to 26 weeks of gestation. In fact, babies can even distinguish their mother’s voice and the general rhythm of their native language before they’re born!
Why is this important? Hearing voices, music, and reading aloud provides sensory stimulation that helps the auditory parts of your baby’s brain develop. As one scientist explained, without exposure to sound, the fetal auditory cortex wouldn’t get enough input to wire itself correctly – the sounds of voices and language actually help the brain form connections. The UK’s National Health Service also encourages parents-to-be to chat and sing to baby bumps, noting that it helps babies tune their hearing and get ready for language, while also making them feel safe and comforted by familiar voices.
Try making it a daily habit to narrate your day, read a story, or sing a lullaby to your unborn baby. You can:
Proper nutrition is critical for brain development! In addition to loading up on healthy eats, make taking a prenatal vitamin—with folic acid!—a priority. Folic acid (the synthetic form of folate, a B-vitamin) is essential to early brain and nervous system formation. It helps the embryonic neural tube close and develop into the baby’s brain and spinal cord. Getting enough folic acid before and during early pregnancy (at least 400 micrograms daily) can prevent major neural tube defects of the brain (like anencephaly) and spine (spina bifida).
At your prenatal appointments your doc will monitor your baby’s growth and your health – including managing conditions like high blood pressure, diabetes, or thyroid issues – which can affect fetal brain development if uncontrolled. Following your doctor’s advice on things like weight gain, vaccinations (e.g. flu shot), and any needed supplements (iron, iodine, vitamin D, etc.) will ensure your baby’s brain is getting all the building blocks and protection it needs. Think of your prenatal appointments as part of your brain-boosting routine: they help catch any issues early so you can address them and give your baby the best possible start.
Drink plenty of water and be cautious with hot tubs or saunas, as excessive heat can be harmful to a developing fetus, especially during early pregnancy. Adequate hydration helps maintain healthy blood flow to the uterus and placenta, delivering oxygen and nutrients that growing brain cells rely on.
Just as positive habits can help your baby’s brain, certain substances and exposures can hurt it. Here are critical habits to avoid for the sake of healthy brain development:
There is no known safe amount of alcohol in pregnancy. Drinking can interfere with the baby’s brain development at any stage and can lead to fetal alcohol spectrum disorders, which involve lifelong cognitive and behavioral impairments. Alcohol is a potent neurotoxin for a developing brain. It can disrupt how neurons form connections and even alter brain structure. If you’re struggling to quit, talk to your provider. Help is available!
Cigarette smoke contains toxic chemicals like nicotine and carbon monoxide that reduce oxygen supply to your baby. Smoking in pregnancy can damage your baby’s developing brain and lungs, with effects that last into childhood. Babies of smokers are at higher risk for learning difficulties, behavioral issues, and Sudden Infant Death Syndrome (SIDS) as well. Studies have even shown that fetuses of smoking mothers have slower growth of the head and brain during pregnancy. Also, avoid secondhand smoke—ask family members to smoke outside away from you.
Illicit drugs like cocaine, methamphetamine, opioids, or excessive cannabis can seriously derail fetal brain growth and cause withdrawal or developmental problems in newborns. Always check with your doctor before taking any medication (even herbal supplements. Also, limit exposure to chemicals that could be neurotoxic. For example, avoid high-mercury fish (like shark or swordfish), steer clear of lead paint or fumes, and use safe cleaning products. Using proper ventilation and gloves for any necessary household chemicals is wise.
Remember, brain development doesn’t stop at birth— it’s an ongoing journey! After birth, keep engaging in responsive, loving interactions…cuddling your baby, making eye contact, smiling, and talking to them. These behaviors release hormones that foster brain growth and secure attachment. Skin-to-skin contact, breastfeeding if you choose, and continuing to read and play will all build on the strong start you gave your little one during pregnancy.

Muttermilch ist die beste Quelle der Ernährung für Babys. Es ist wichtig, dass Mütter in Vorbereitung auf das Stillen und währenddessen eine gesunde, ausgewogene Ernährung zu sich nehmen. Die Kombination von Stillen und Flaschenernährung in den ersten Lebenswochen kann die Muttermilchversorgung verringern und die Entscheidung, nicht zu stillen, ist schwer rückgängig zu machen. Wenn Sie sich entscheiden, Säuglingsnahrung zu verwenden, sollten Sie die Anweisungen sorgfältig befolgen.
