I was over at my parents and while DS was sleeping in the bouncer I kept checking on him...
I asked my Mom, "So when do I stop worrying so much that he's not breathing and just let him sleep? How long will I constantly check on him???"
My Mom just looked at me and said "When YOU spent the night 2 months ago, I checked on YOU"... I'm 33
So I guess I'm resigning myself to worry forever!
