No, your baby didn’t really grow 4 inches since last week. He’s just being measured differently. For the first half of pregnancy (when a baby’s legs are curled up against his torso), measurements are taken from the top of his head to his bottom, or from “crown to rump.” But starting at 20 weeks, he’s measured from head to toe.
Taste buds in training
Many of your baby’s taste buds can now transmit taste signals to his brain, and he’s swallowing molecules of the food you eat that have passed through your blood into your amniotic fluid. Researchers aren’t sure if he can taste these molecules, but some research indicates that what you eat during pregnancy can influence the foods your baby will prefer later.
