My Baby: Your little one has hiccups! An involuntary movement of the diaphragm causes these painless contractions. In adults, this movement is followed by closure of the vocal cords (making the familiar "hic" noise); because the baby's trachea is filled with fluid rather than air, fetal hiccups don't generate sound. The frequency of hiccups varies widely, with some babies experiencing several bouts a day and others never seeming to get them at all. By the sixth month, you'll be able to "see" fetal hiccups as they occur--they'll make your belly jump. Baby's Size: Rubber Ducky Baby's Length: 4.5-5 in. Baby's Weight: 2.5- 3 oz. How your baby's growing: Get ready for a growth spurt. In the next few weeks, your baby will double his weight and add inches to his length. Right now, he's about the size of an avocado: 4 1/2 inches long (head to rump) and 3 1/2 ounces. His legs are much more developed, his head is more erect than it has been, and his eyes have moved closer to the front of his head. His ears are close to their final position, too. The patterning of his scalp has begun, though his locks aren't recognizable yet. He's even started growing toenails. And there's a lot happening inside as well. For example, his heart is now pumping about 25 quarts of blood each day, and this amount will continue to increase as your baby continues to develop.
