22 Weeks

At 11 inches (the length of a spaghetti squash) and almost 1 pound, your babies are starting to look like a miniature newborn. Their lips, eyelids, and eyebrows are becoming more distinct, and they're even developing tiny tooth buds beneath their gums. Their eyes have formed, but their irises (the colored part of the eye) still lack pigment. If you could see inside your womb, you'd be able to spot the fine hair (lanugo) that covers their bodies and the deep wrinkles on their skin, which they'll sport until they add a padding of fat to fill them in. Inside their bellies, their pancreas — essential for the production of some important hormones — is developing steadily.
