Week 7
Your baby is now about the size of a blueberry. Most of that growth is concentrated in the he. his arm and leg buds sprout, and those little kidneys are getting ready to do their job.http://www.babycenter.com -
week 9
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.http://www.babycenter.com -
Week 12
Your baby's fingers will soon begin to open and close, his toes will curl, his eye muscles will clench, and his mouth will make sucking movements. His intestines, which have grown so fast that they protrude into the umbilical cord, will start to move into his abdominal cavity about now.http://www.babycenter.com -
week 14
This week's big developments: Your baby can now squint, frown, grimace, pee, and possibly suck his thumb. Thanks to brain impulses, his facial muscles are getting a workout as his tiny features form one expression after another. His kidneys are producing urine, which he releases into the amniotic fluid around him. -
Week 18
He's busy flexing his arms and legs — movements that you'll start noticing more and more in the weeks ahead. His blood vessels are visible through his thin skin, and his ears are now in their final position, although they're still standing out from his head a bit. A protective covering of myelin is beginning to form around his nerves, a process that will continue for a year after he's born.http://www.babycenter.com -
week 24
He cuts a pretty lean figure at this point, but his body is filling out proportionally and he'll soon start to plump up. His brain is also growing quickly now, and his taste buds are continuing to develop. His lungs are developing "branches" of the respiratory "tree" as well as cells that produce surfactant, a substance that will help his air sacs inflate once he hits the outside world. His skin is still thin and translucent, but that will start to change soon.http://www.babycenter.com -
week 27
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. Chalk up any tiny rhythmic movements you may be feeling to a case of baby hiccups, which may be common from now on. Each episode usually lasts only a few moments.http://www.babycente -
week 32
In fact, she'll gain a third to half of her birth weight during the next 7 weeks as she fattens up for survival outside the womb. She now has toenails, fingernails, and real hair. Her skin is becoming soft and smooth as she plumps up in preparation for birth.http://www.babycenter.com -
week 33
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.These bones don't entirely fuse until early adulthood, so they can grow as his brain and other tissue expands during infancy and childhood.http://www.babycenter.com -
week 38
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, they may stay gray or blue or turn green, hazel, or brown by the time she's 9 months old.http://www.babycenter.com
