24 Weeks

Your baby's growing steadily, gaining about a quarter of a pound since last week, when he was just over a pound. Since he's almost a foot long (picture an ear of corn), that makes a pretty lean figure, but his body is filling out proportionally and he'll soon put on more baby fat. Your baby's skin is thin, translucent, and wrinkled, his brain is growing rapidly, and his taste buds are developing. His lungs are developing "branches" of the respiratory "tree" and cells that produce surfactant, a substance **that helps the air sacs inflate easily.
As you can tell from the picture Brayden is growing nicely. I have started experiencing some physical pains from all the growing- the sciatic nerve (located nicely in the butt) hurts a lot, and now some lower back pain. The doctor says it is due to the pelvis widening, and all the back muscles and tendons softening to move everything around. It is crazy how much your body adapts to having a baby!
