week 7
The big news this week: Hands and feet are emerging from developing arms and legs — although they look more like paddles at this point than the tiny, pudgy extremities you're daydreaming about holding and tickling. Technically, your baby is still considered an embryo and has something of a small tail, which is an extension of her tailbone

week 9
Your new resident is nearly an inch long — about the size of a grape — and weighs just a fraction of an ounce. She's starting to look more and more human. Her essential body parts are accounted for, though they'll go through plenty of fine-tuning in the coming months. Other changes abound: Your baby's heart finishes dividing into four chambers, and the valves start to form — as do her tiny teeth

week 11
Your baby, just over 1 1/2 inches long and about the size of a fig, is now almost fully formed. Her hands will soon open and close into fists, tiny tooth buds are beginning to appear under her gums, and some of her bones are beginning to harden

week 13
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 (the size of a medium shrimp) and weighs nearly an ounce

week 17
Your baby's skeleton is changing from soft cartilage to bone, and the umbilical cord — her lifeline to the placenta — is growing stronger and thicker. Your baby weighs 5 ounces now (about as much as a turnip), and she's around 5 inches long from head to bottom. She can move her joints, and her sweat glands are starting to develop.

week 19
Your baby's sensory development is exploding! Her brain is designating specialized areas for smell, taste, hearing, vision, and touch. Some research suggests that she may be able to hear your voice now, so don't be shy about reading aloud, talking to her, or singing a happy tune if the mood strikes you.

week 21
Your baby now weighs about three-quarters of a pound and is approximately 10 1/2 inches long — the length of a carrot. You may soon feel like she's practicing martial arts as her initial fluttering movements turn into full-fledged kicks and nudges. You may also discover a pattern to her activity as you get to know her better

week 27
This week, your baby weighs almost 2 pounds (like a head of cauliflower) 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 tissue developing, 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

week 31
This week, your baby measures over 16 inches long. He weighs about 3.3 pounds (try carrying four navel oranges) and is heading into a growth spurt. He can turn his head from side to side, and his arms, legs, and body are beginning to plump out as needed fat accumulates underneath his skin

week 35
Your baby doesn't have much room to maneuver now that he's over 18 inches long and tips the scales at 5 1/4 pounds (pick up a honeydew melon). Because it's so snug in your womb, he isn't likely to be doing somersaults anymore, but the number of times he kicks should remain about the same.

week 39
Your baby's waiting to greet the world! He continues to build a layer of fat to help control his body temperature after birth, but it's likely he already measures about 20 inches and weighs a bit over 7 pounds, a mini watermelon. (Boys tend to be slightly heavier than girls.) The outer layers of his skin
