The Fruit: 21 weeks

Baby gulps down several ounces of amniotic fluid every day, both for hydration and nutrition and to practice swallowing and digesting. And, these days, those taste buds actually work! Studies show that after birth, babies are most interested in tastes they've already experienced through amniotic fluid. Meaning, think about what you want your future child to eat as you prepare your own lunch.

(So, I should really try to cut back on the Cocoa Krispies and Sweettarts this week? Fine.)
