Not sure what to call this post

I am not sure why I am posting about this because I should not be encouraging this behaviour. Anyway I was busy getting ready for our Missori trip when the boys come upstairs and say "Look mom I got Boobs" then came the question
Noah: Are mine Bigger then yours, because I know they are bigger then Lucy's
Me: Yes, they are bigger
What do I say to that, I mean really.
The best part was when one of Sam's fell and he says "Mom my Boob broke" I couldn't help but laugh a little.
Everyday definatly is an adventure with these two.
