Week Twenty Eight: May recognize your voice
You are 28 weeks pregnant. (fetal age 26 weeks)
Brain waves show rapid eye movement (REM) sleep, which means your baby may be dreaming. Eyelids are opening. Eye color may change within the first six months of life especially if your baby’s eyes are blue or gray-blue at birth. Remember to talk to your baby often; reading stories, singing songs has been seen to slow the baby’s heart rate. He or she can recognize your voice now and will often calm to it later after birth.
Your uterus will be about 3 inches (7cm) above your bellybutton. During this time of your pregnancy, your belly will grow about half an inch (1cm) each week. If you have been following a nutritious, balanced meal plan, your total weight gain is probably between 17 and 24 pounds (7.5 and 10.5 Kg).
Branches of lungs are quite developed now, so there is a good chance that baby would survive if born prematurely now. If your baby is born this week, the chances of survival is now at least 90 percent. However, some complications are still possible.
It’s a big week in the life of your little baby. Her eyes, which have been fused shut until about now, open and she begins to blink. The irises don’t have any pigment yet; they’re a slate grey. But her pupils will react to different levels of light by contracting and dilating. And she may respond to a bright light from outside by giving a little kick. Your baby already looks a lot like she will appear at birth. She’s still quite wrinkly though, because of being surrounded by the amniotic fluid.
Her respiratory system is still very immature (were she to be born now she would still need very intensive care and lots of intervention and help with breathing), but it has developed to the point where gas exchange is possible.
By this week, your baby weighs two and a quarter pounds (like a Chinese cabbage) and measures 14.8 inches from the top of her head to her heels. She can blink her eyes, which now sport lashes. With her eyesight developing, she may be able to see the light that filters in through your womb. She’s also developing billions of neurons in her brain and adding more body fat in preparation for life in the outside world.
Baby’s now the size of an eggplant!
Baby’s lungs are mature enough that, if born right now, she has a pretty good chance of surviving (with help from medical technology). Her skin is still pretty wrinkly (one byproduct of living in amniotic fluid) but will smoothen as fat continues to deposit.
