Mommy, I'm like an apple (10cm, 70 grams)

My hearing develops significantly - inner ear structures are mature enough that I can hear sounds from outside, especially low frequencies like your voice, heartbeat, and bowel sounds. This is the first sense to fully develop! Bones become hard enough to be visible on an X-ray. My lower limbs are now longer than upper ones, bringing me closer to newborn proportions. Hair on my head begins growing in specific patterns - even the color is already genetically determined. My liver begins producing bile in larger quantities, visible as greenish coloring of amniotic fluid.

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.
