Week 24

Baby is growing steadily, having gained about 4 ounces since last week. That puts baby at just over a pound. Since he/she is almost a foot long (picture an ear of corn), he/sh cuts a pretty lean figure at this point, but his/her body is filling out proportionally and he'll/she'll soon start to plump up. His/her brain is also growing quickly now, and taste buds are continuing to develop. Lungs are developing "branches" of the respiratory "tree" as well as cells that produce surfactant, a substance that will help the air sacs inflate once he/she hits the outside world. Skin is still thin and translucent, but that will start to change soon.
