Weeks 1 - 9


After fertilization and implantation, your baby grows quickly. At first she's just an embryo, consisting of two layers of cells from which all her organs and body parts will develop. Soon she's about the size of a kidney bean and constantly moving. Her heart is beating quickly and her intestines are forming. Her earlobes, eyelids, mouth, and nose are also taking shape.



Weeks 10 - 14


At 13 weeks, fingerprints have formed on your baby's tiny fingertips, her veins and organs are clearly visible through her still-thin skin, and her body is starting to catch up with her head — which makes up just a third of her body size now. If you're having a girl, she now has more than 2 million eggs in her ovaries. Your baby is almost 3 inches long (about the size of a pea pod) and weighs nearly an ounce.

Weeks 15 - 20 


In the beginning of the second trimester, your baby is about 3 1/2 inches long and weighs about 1 1/2 ounces. His tiny, unique fingerprints are now in place. As the weeks go by, his skeleton starts to harden from rubbery cartilage to bone and he develops the ability to hear. You're likely to feel your baby's kicks and flutters soon if you haven't already.



Weeks 21 - 27


This week, your baby weighs almost 2 pounds and is about 14 1/2 inches long with her legs extended. She's sleeping and

waking at regular intervals, opening and

closing her eyes, and perhaps even

sucking her fingers. With more brain

tissuedeveloping, your baby's brain is

very active now. While her lungs are still

immature, they would be capable of

functioning — with a lot of medical help

— if she were to be born now. Chalk up

any tiny rhythmic movements you may

be feeling to a case of baby hiccups,

which may be common from now on.


Weeks 28 - 37


When you enter your third trimester, your baby weighs about 2 1/4 pounds. She can blink her eyes, which now sport lashes. Her wrinkled skin is starting to smooth out as she puts on baby fat. She's developing fingernails, toenails, and real hair (or at least some peach fuzz), and adding billions of neurons to her brain. She'll spend her final weeks in utero putting on weight. At full term, the average baby is more than 19 inches long and weighs nearly 7 pounds.
