Mommy, I'm like a large mango (28.9cm, 501 grams)

My balance organ in the inner ear is fully developed - I know exactly when I'm upside down, on my side, or head down! Skin is still wrinkled and reddish because I don't have enough subcutaneous tissue yet, but this will change quickly. If I'm a boy, testes begin their journey from the abdominal cavity through the inguinal canal to the scrotum. My brain grows at a rate of 250,000 neurons per minute, and the first folds and grooves begin forming on the cerebral cortex surface. Lungs produce increasing amounts of surfactant, though still not enough for independent breathing.

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.
