K.F.
I did this a few months ago with my 2 year old son, and my daughter was 9 months at the time. We had the same situation with life moving so quickly. My son was 8 months old when I got pregnant with my daughter. I decided early on to just wait to have my son Baptized until after my daughter was born so we could do them together. Everything went great and we threw a big party afterwards for both of them!
