It's a BOY!!
We took the two older kids to the ultrasound today and as soon as the technician told us it's a boy, Jonah starting jumping up and down and yelling! Ava's reaction was a little different; she just sat quietly.
Everything looks great and the baby is very healthy. Hopefully he won't be as big as Jonah was at birth, but we are very blessed to have him and now we have a girl sandwich.
