I love plums!

By now, your baby weighs a full half-ounce and is about the size of a large plum. Most of his systems are in place, though there's still plenty of maturing to do. For one thing, his fetal digestive system is beginning to practice contraction movements so he can eat someday, and his bone marrow is busy making white blood cells — weapons against germs once he's out of your safe haven. The pituitary gland (at the base of the brain) has started producing the hormones that'll enable him (or her) to make babies of his (or her) own in a couple of decades or so.
