Baby Lack-Update 7

Week 28-By this week, your baby weighs two and a quarter pounds (like a Chinese cabbage) and measures 14.8 inches from the top of his head to her heels. He can blink his eyes, which now sport lashes. With his eyesight developing, he may be able to see the light that filters in through your womb. He's also developing billions of neurons in his brain and adding more body fat in preparation for life in the outside world.

Week 27-This week, your baby weighs almost 2 pounds (like a head of cauliflower) and is about 14 1/2 inches long with his legs extended. He's sleeping and waking at regular intervals, opening and closing his eyes, and perhaps even sucking his fingers. With more brain tissue developing, your baby's brain is very active now. While his lungs are still immature, they would be capable of functioning — with a lot of medical help — if he 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, and they don't bother him, so just relax and enjoy the tickle.

Week 26-The network of nerves in your baby's ears is better developed and more sensitive than before. He may now be able to hear both your voice and your partner's as you chat with each other. He's inhaling and exhaling small amounts of amniotic fluid, which is essential for the development of his lungs. These so-called breathing movements are also good practice for when he's born and takes that first gulp of air. And he's continuing to put on baby fat. He now weighs about a pound and two-thirds and measures 14 inches (an English hothouse cucumber) from head to heel. If you're having a boy, his testicles are beginning to descend into his scrotum — a trip that will take about two to three days.
