trimester. Weeks 13-24 should be easier than the first few
months because your body has adjusted to full "baby growing"
mode.Your baby weighs about 1 ounce and is about 3 inches in
length. Your baby's digestive tract continues to develop as
inside the intestines tiny villi (hairs) are forming. These
villi will assist in moving the food through your baby's
digestive tract. The pancreas has begun producing insulin
and within your baby's mouth, all 20 teeth have evolved but
of course are not visible. (That would make predicting
orthodontist bills way too easy?)

Your belly may soon be big enough to announce to the world that you're expecting, but your baby is still tiny. In fact, he's only about 3 inches long crown to rump — roughly the size of a jumbo shrimp — and weighs just about an ounce. Despite the small proportions, there's a fully formed baby inside your womb now. Much more proportional than it was a few weeks ago, his head is now only about a third the size of his body. His tiny, unique fingerprints are already in place. His kidneys and urinary tract are functional, and he's starting to urinate out the amniotic fluid he's been swallowing. As you start your second trimester, most of your baby's critical development will be completed, and your odds of miscarriage will drop considerably.
