Hearing your heartbeat
Your baby may be able to hear sounds faintly from inside your body, such as your breathing, your heartbeat, and your digestion. These sounds will grow louder as your baby’s hearing improves.
Hairy and wrinkly
If you could see inside your womb, you’d be able to spot the fine hair (lanugo) that covers his body and the deep wrinkles on his skin, which he’ll sport until he adds a padding of fat to fill them in.
