Some young children are brutally honest. They just haven't learned how to be tactful with their comments. It's the older ones that know better that you feel like slapping.

Sort of off topic...what is it with new Mommies? (and this isn't meant to completely generalize new mommies but a few I've come across have acted this way.) My SIL just had her first baby about 4 months ago. I love her child(my godchild) dearly. Well at lunch the other day she was telling me about how Abby's bottle got switched at the nursery. I must have looked bored, because she said to me, "You'll understand when your a Mommy."

I had to grit my teeth. I know she doesn't realize how condescending she sounds. But why is it all the sudden, she has this Mother knows best attitude for everyone? And it's not just about the baby...suddenly she's an authority on everything. And I never call her on it because I know she just loves being a Mommy and maybe this is just part of it, but I swear if I ever get that patronizing to anyone after I have a child or god forbid say, "You'll understand when you're a Mommy.", somebody slap me.
