Madelyn is crawling a few "steps" at a time now, pulling up on everything, and has figured out how to untie her crib bumper. She does NOT want to lie down to have her diaper changed so I'm trying to figure out how to do it while she's sitting....yeah, it's just as tricky as it sounds. And, we've experienced our first few temper tantrums when she can't get to the toy she wants. I am not ready for this!!!
