Anyone else having baby #3?

Hi! This will be our 3rd child ( don't know how many are in there yet!). Our son is 10 and our daughter is 5. I think I will tell the kids around Christmas time, maybe Christmas eve would be fun. I want to find a fun and creative way to let them know our family is growing. My daughter recently said she wanted to talk to God about having a baby brother...lol!

On another note, I am a bit scared about having a miscarriage. I am 34 and want to have a healthy pregnancy and baby but with my age I just don't know what to expect....
