The first and last pictures are Shiloh. Looking at some other pictures of Shiloh when she was first born, I think they have a lot of the same features, but his are more pronounced. Same chubby cheeks (his are bigger), same (close enough anyway) nose (his is bigger), same lips, and it looks like he's going to have a very round head just like she did.
Shiloh and I are going to take a trip to the hospital a little later. We should learn his name, height, weight, etc. and, of course, we'll get more pictures! So check back later. The only thing I know is he was born sometime before 11:15 last night. He was three days past his due date, just like Shiloh!
