Week 25

Baby McDonald weighs in at 1 1/2 to 2 pounds this week, and measures about a foot from head to toe. Though still skinny and wrinkly (skin hangs loosely until the fetus develops more baby fat), he's growing rapidly and starting to fill the space in your uterus. You'll feel his kicks and pokes more strongly with each passing week, with kick-strength peaking in about a month when he gets too crowded to do anything but squirm.
