What does a baby look and do when you are 7 months pregnant?

They are completely normal looking, even having hair and eyebrows/eyelashes.
Seven-month-old fetuses are sometimes not even considered premature, as they often have the ability to survive perfectly fine outside the womb. Fetuses have been known (in rare cases, mind you) to survive healthily after only just over five months of pregnancy.

They have normal responses and whatnot; many will even turn toward a light shone on their mothers' pregnant bellies.
