Week 21: Banana

Average size: 10.5 inches ***, 12.7 oz.

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.

Baby's now the size of a banana!
Baby's digestive system is busy creating meconium (a tarry black substance made of swallowed amniotic fluid, digestive secretion, and dead cells), which will fill the first diaper after birth. And, if baby is a girl, her womb is now stocked up with her lifetime supply of six million eggs (the number will drop to around one million by birth).
