BABY Baby continues to accumulate fat, and is getting accustomed to hearing what’s going on in the outside world. It’s about the size of a large mango or grapefruit.

BABY Baby is filling out; in fact, there’s a major growth spurt going on. The skin is becoming opaque, and the face is fully formed with all its features in the right places (phew!).

BABY The lungs are developing rapidly and the nostrils are opening… baby is getting ready to breathe.

BABY The brain development is intense, and so is growth. But most exciting this week: baby will soon open its eyes for the first time. Not that there’s much to see in there.

BABY Now over a foot long (though tucked into the fetal position), baby’s showing brain activity and may even be dreaming already. Hiccups are happening sometimes.

BABY As your baby gets bigger, there’s less room to move around in there — so, fewer somersaults. But junior’s practicing lots of smaller movements, like blinking, sucking, turning of the head, and breathing. And still kicking (as mom well knows).

BABY Baby is about the size of your average butternut squash, but is only about half (or less) of its full-term weight. Calcium is accumulating in the bones, making its skeleton harder.

BABY Fat tissue is building up to regulate body temperature and protect the organs. The skin is smoothing out while the brain is getting wrinkles.

BABY Baby is still growing like crazy (so what else is new?), mostly plumping up. The senses are working and the brain is developing rapidly.

BABY It’s getting pretty cramped in the womb. As of this week, baby would likely be OK if born prematurely, and, in fact, is heading for the exit (settling into the head-down birth position, that is… hopefully!). Ideally, it’ll take 7 or 8 weeks to get there!
