My daughter has a new thing. She won't let me change her diaper. I plead, I beg, I even threaten and she screams!!! That's not even the hard part. When she does let me change her diaper, she won't let me wipe her. She'll lay down, let me take it off and then wiggles around until she's standing up. Not so bad when it's just pee, but this goes on for poopy too. I try not to get mad and gently coax her into letting me wipe her standing up. Do you know how hard it is to get her All clean? I've tried bribing her with stickers, threatening her with a time out, distracting her with a video, singing to her, etc. Any suggestions for nipping this bad behavior in the butt?
