A word about babies!

Lately Kayden has been telling me about a baby sister that he is going to have. I don't know where he is getting this idea from. No there are no announcements...I still have a baby! I think it might be from all of our pregnant friends but I'm not sure. Here is how one of our converstaions went:

Kayden: talking about a baby sister...
Me: Where is your baby sister?
Kayden: in Your belly
Me: How did she get in there?
Kayden: You ate her

I have no idea where he gets this stuff from
So for all you prego moms out there will you please stop eating the babies??
