Baby development at week 28
Welcome to the third trimester. The fetus can now blink, dream (REM sleep is present), and its eyelashes have grown in. The brain is developing deep grooves and ridges to make room for more tissue, and the lungs are mature enough that survival odds are good with care if birth happened now. Body fat continues to build.
