Baby's 3rd Trimester Development


Dr. O’Connor

By the end of the seventh month, your baby is beginning to get some fat on her body and she probably weighs about three pounds. She can respond to sound and touch, and she may even suck her thumb. You’ll feel her move around quite a bit at this point.

Over the coming weeks, her body, and especially her brain, will grow more than ever. By 32 weeks, most of her body’s systems are well developed, although her lungs still need time to prepare for the outside world.

During your last month of pregnancy, your baby is getting ready for birth. She’ll gain as much as two and a half pounds and grow about two inches during the final weeks. At this stage, your baby might not move quite as much.  If she really slows down a lot or you’re concerned she’s not moving enough, contact your provider.
