Mommy, I'm like a large cauliflower (36.6cm, 875 grams)
I'm entering the third trimester - the final stretch before our meeting! My brain activity is very similar to newborn patterns, with distinct REM sleep and deep sleep phases. I can even have dreams! Lungs produce significantly more surfactant, though still not enough for completely problem-free breathing. Regular breathing movements I perform help strengthen the diaphragm and intercostal muscles. Fatty tissue begins accumulating faster, which will help me maintain body temperature after birth. My brain grows so fast that its mass doubles every month.
Remember mom, every child develops at their own pace and has their unique timeline. If you have any doubts about my development in your belly, consult with a doctor.
