Week 7
Your baby is about the size of a blueberry. Most of that growth is concentrated in the head as new brain cells are generated at the rate of 100 per minute. Your babys mouth is now forming as its arms and legs are sprouting. -
Week 11
Your baby now about two inches long.She has distinct human characteristics by now, with hands and feet in front of her body, with ears nearly in their final shape, open nasal passages on the tip of her tiny nose, a tongue and palate in the mouth, and visible nipples. -
Week 14
This week's big developments: Your baby can now squint, frown, grimace, pee, and possibly suck his thumb. His kidneys are producing urine.His body's growing faster than his head, which now sits upon a more distinct neck. -
Week 19
Her brain is designating specialized areas for smell, taste, hearing, vision, and touch. She may be able to hear your voice now.Your baby weighs about 8 1/2 ounces and measures 6 inches. -
Week 23
With her sense of movement well developed by now, your baby can feel you dance. She's more than 11 inches long and weighs just over a pound.Blood vessels in her lungs are developing to prepare for breathing, and the sounds that your baby's increasingly keen ears pick up are preparing her for entry into the outside world. -
Week 26
The network of nerves in your baby's ears is better developed and more sensitive than before. He may now be able to hear both your voice and your partner's as you chat with each other. He's inhaling and exhaling small amounts of amniotic fluid, which is essential for the development of his lungs. -
Week 30
Your baby's about 15.7 inches long now, and she weighs almost 3 pounds. A pint and a half of amniotic fluid surrounds her, but that volume will decrease as she gets bigger and takes up more room in your uterus.Her eyesight continues to develop, though it's not very keen; even after she's born, she'll keep her eyes closed for a good part of the day. -
Week 33
Your baby is still gaining weight (about half a pound a week), and she could grow up to another full inch this week.With that much baby inside your uterus, your amniotic-fluid level has maxed out, which explains why some of her pokes and kicks feel pretty sharp these days.Antibodies are being passed from you to your little one as she continues to develop her own fetal immune system, which will come in handy once she's outside the womb and fending off all sorts of germs. -
Week 37
Your baby is now considered "full term," even though your due date is three weeks away. If you go into labor now, his lungs will likely be mature enough to fully adjust to life outside the womb.Your baby weighs 6 1/3 pounds and measures a bit over 19 inches. -
Week 40
The average newborn weighs about 7 1/2 pounds.His skull bones are not yet fused, which allows them to overlap a bit if it's a snug fit through the birth canal during labor.This so-called "molding" is the reason your baby's noggin may look a little conehead-ish after birth. Rest assured — it's normal and temporary.
