Week 6
Your baby's jaw, cheeks, chin, eyes, ears, and nose are beginning to form what will eventually become one adorable face. In addition, her kidneys, liver, and lungs are developing, and her heart is now beating 80 times a minute (and getting faster every day). All this and she's still no bigger than the length of a nail head (about a quarter of an inch) from crown to rump! -
Week 9
Your baby, now the size of a green olive, has grown about an inch since last week. It's still too soon to feel anything in your belly, but you might be able to hear something at your next checkup.Tiny muscles are beginning to form, so while he might not be ready to pump iron, he's gearing up to move his arms and legs.

Week 12
By now, your baby weighs a full half-ounce and is about the size of a large plum.Most of his systems are in place, though there's still plenty of maturing to do.His bone marrow is busy making white blood cells — weapons against germs once he's out of your safe haven.

Week 15
She's about the size of an orange this week, her ears have migrated to the sides of her head, and her eyes are moving to the front of her face. Plus, your little smarty-pants can now wiggle her fingers and toes and make breathing movements in preparation for life outside the womb.You might not yet be feeling it, but your baby is kicking those little legs and flexing those elbows.

Week 20
Curious about whether that melon-sized belly contains a boy or a girl? Now's your chance to take a peek! And while your baby is definitely getting bigger (weighing in at about ten ounces and measuring six and a half inches), there's still plenty of growing room in there. This allows him to twist and turn (and allows you to feel his acrobatics!).

Week 24
Your baby is about eight and a half inches long and weighs one and a half pounds, gaining steadily at a rate of six ounces per week. Much of that weight comes from accumulating baby fat, as well as from growing organs, bones, and muscle. Those little ears can hear very loud sounds, from a yapping dog to a jackhammer. By now, that fabulous face is almost fully formed, complete with eyelashes, eyebrows, and hair.

Week 28
Your baby is settling into the proper position for birth, with his head facing downward (toward your body's nearest exit!). Your little work in progress is now about 2.5 pounds and almost 16 inches long. He's busy adding new skills such as blinking to an already impressive repertoire of tricks like coughing, sucking,
hiccuping, and taking practice breaths.

Week 32
She's starting to get ready for her big debut, tipping the scales at almost four pounds and topping out at just about 19 inches. In these past few weeks, it's all about practice, practice, practice as she hones the skills she'll need to thrive outside the womb — from swallowing and breathing to kicking and sucking. And speaking of sucking, your little one has been
able to suck her thumb for a while now.

Week 36
Your baby is now about six pounds and 20 inches long. She has soft bones and cartilage to allow a safer journey through the exit door.You should still feel her moving, but there will be less jabbing and kicking, and a lot more squirming.

Week 40
This week marks the official end of your pregnancy. Your baby probably weighs anywhere from six to nine pounds and measures between 19 and 22 inches (though tons of perfectly healthy babies are smaller or bigger). The bones in his skull haven’t fused yet — Mother Nature’s way of making it easier to get through the birth canal during labor and delivery.
