9 Weeks

I don't have a book about twins but I read my singleton pregnancy book this morning and here are a few things happening with our babies this week. The babies are nearly an inch long — They are about the size of a grape(that is so tiny still)— and they weigh just a fraction of an ounce each now. They are starting to look more and more human(which is evident in my baby ticker, those babies are so darn cute). Their essential body parts are accounted for, though they'll go through plenty of fine-tuning in the coming months. The babies hearts finish dividing into four chambers, and the valves start to form — as do their tiny teeth. The embryonic "tail" is completely gone. Both babies organs, muscles, and nerves are kicking into gear. Their external sex organs are there but won't be distinguishable as male or female for another few weeks...darn I really want to know now!

The most exciting thing happening this week is our ultrasound tomorrow so be on the watch for new photos of our twins!
