An interesting fact: first-time moms under 30 are the most likely to have problems with twin pregnancies, which is exactly opposite of single pregnancies.
At the ultrasound, though, they said the babies are doing great! They're growing perfectly, moving perfectly ... and here's a picture of A's face! It's not great quality, but I think you will be able to discern her fat little cheeks and big lips. :) The white part by her nose is her nasal bone structure. B was facing my back yesterday, so we didn't get to see her face.
There's nothing like a picture of the babies to brighten my spirits, even with all the discouraging news. :) Keep on praying for us!
