Responds to Sound
Here’s what Baby’s baby was up to on January 2...
- The head is now the size of a tennis ball.
- The inner ear is already fully developed and fully grown.
- If born prematurely this week, the chance of survival is about 40% with expert medical care!
- Hearing begins, as does response to sound.
- All skin layers and structures are complete.
- The eyelids separate, and eyes open and close.
