week 3
Well, at 3 weeks pregnant your baby doesn't really resemble a baby at all. Instead, it started this week as a small collection of cells (a handful at first, but multiplying rapidly from here on in), known as a zygote. It goes through a few stages over the next few days, eventually becoming a blastocyst as it travels through the fallopian tube to the cavity of the uterus, where it will float freely as it continues to develop. http://www.surebaby.com/pregnancy-and-birth/week-by-week/pregnancy-week -
week 7
The baby's eyes and inner ears are starting to develop. It is about now that your baby's major organs (heart, lungs liver, spleen, and kidneys) are beginning to develop. Your baby's digestive system is becoming more refined as the stomach and intestines develop. Remember the Folic Acid you should be taking? Well, since the Neural tube (later known as spinal cord) begins to fuse, folic acid is important in preventing neural tube defects. The embryo size is about a 1/8 inch (4mm) long http://baby2 -
week 10
Though he's barely the size of a kumquat — a little over an inch or so long, crown to bottom — and weighs less than a quarter of an ounce, your baby has now completed the most critical portion of his development. This is the beginning of the so-called fetal period, a time when the tissues and organs in his body rapidly grow and mature. He's swallowing fluid and kicking up a storm. http://www.babycenter.com/6_your-pregnancy-10-weeks_1099.bc -
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. http://www.babycenter.com/6_your-pregnancy-13-weeks_1102.bc -
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. Your baby weighs about 8 1/2 ounces and measures 6 inches, head to bottom — about the size of a large heirloom tomato. http://www.babycenter.com/6_your-pregnancy-19-weeks_1108.bc -
week 23
Your baby is more than 11 inches long and weighs just over a pound (about as much as a large mango). His skin is red and wrinkled. Blood vessels in his lungs are developing to prepare him for breathing. He can swallow, but he normally won't pass his first stool (called meconium) until after birth. Loud noises -
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. http://www.babycenter.com/6_your-pregnancy-27-week -
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. He's probably moving a lot, too, so you may have trouble sleeping because your baby's kicks and somersaults keep you up. Take comfort: .http://www.babycenter.com/6_your-pregnancy-31-weeks_1120.bc -
week 33
This week your baby weighs a little over 4 pounds (heft a pineapple) and has passed the 17-inch mark. He's rapidly losing that wrinkled, alien look and his skeleton is hardening. The bones in his skull aren't fused together, which allows them to move and slightly overlap, thus making it easier for him to fit through the birth canal. (The pressure on the head during birth is so intense that many babies are born with a conehead-like appearance.)This week your baby weighs a little over 4 pounds (he -
week 38
Your baby has really plumped up. She weighs about 6.8 pounds and she's over 19 1/2 inches long (like a leek). She has a firm grasp, which you'll soon be able to test when you hold her hand for the first time! Her organs have matured and are ready for life outside the womb. Wondering what color your baby's eyes will be? You may not be able to tell right away. If she's born with brown eyes, they'll likely stay brown. If she's born with steel gray or dark blue eyes,http://www.babycenter.com/6_you
