Your baby's growing steadily, having gained about 4 ounces since last
week. That puts him at about 1 1/3 pounds. Since he's almost a foot long
(
about the size of an ear of corn),
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.
