It's never a good thing when your one-year-old son gives his friend a bloody lip. Let me give you the play-by-play: she can walk, he can't, so he headbutted her in a fit of frustration.
My Mother-in-law thinks it's God's sense of humor that I had a boy and ALL of my friends have girls.
Freaking hilarious. I'm going to be the Mom that's not invited to playgroup anymore.
