I should add to my previous post that Elaine hasn't regressed in terms of potty training but I have, apparently. After assisting her in the bathroom, I grabbed a diaper and started putting it on her.
"Mommy, what are you doing?"
I think I just looked confused for a moment. I'd checked to make sure I grabbed a newborn size, not size 1. Then it hit me, "Oh right. You don't wear diapers." In fact, she hasn't worn diapers of any kind day or night in 5 months. I'm clearly a little short on sleep these days.
