BABY Your baby is about as long as a pea pod, and already has fingerprints. (Imagine how tiny those fingertips are!) The body is growing bigger in proportion to the head.

BABY It’s getting hairy in there! Baby is growing hair on the scalp and eyebrows, along with soft, all-over, temporary baby fuzz (called lanugo), and is moving around, peeing, and making facial expressions.

BABY Now about the size of an apple, baby might be sucking its thumb. How sweet is that?! There’s also lots of kicking and wriggling going on.

BABY Baby is now “breathing” amniotic fluid. The ears are developing, and so is baby’s sense of hearing.

BABY There’s a growth spurt going on: cartilage is becoming bone, fat is forming. For now, baby is about the size of an onion.

BABY Baby is busting a move! Kicking, rolling, stretching, punching, flexing, twisting, yawning, sucking, swallowing… it’s like baby training camp in there.

BABY Baby is about the size of a mango this week. The senses are developing rapidly, and a protective coating called vernix (now, there’s a good Scrabble word) is forming on the skin.

BABY The legs aren’t curled up against the torso any more, so baby is measured from head-to-heel instead of head-to-rump from now on. This week’s food comparison is… a banana!

BABY Your baby weighs roughly the same as a can of soup and is steadily gaining fat. Junior is asleep at least half the time, but when awake he’s enjoying swimming around while there’s still room.

BABY Weighing in at about a pound (like a brick of butter), your baby is looking more like… well, a baby. Junior responds to sound (including rhythm and melody) and is looking for things to hold onto as the grip and sense of touch develop.
