Juliana just turned three this week, but she has been completely potty trained for at least the last 6-8months. Well today she has an accident on the living room floor. I don't freak out b/c I understand that accidents happen.
Two hours later she comes into my room babbling on about a diaper I tell her that she's a big girl and she doesn't wear diapers anymore. 10mins later she comes back in to my room trying to put on a diaper that she found in her closet. Again, I give her the big girl speech. She throws a tantrum- but thats nothing new so I didn't think anything of it.
I go back into the living room and there she is squatting on the floor again. WTF??
I take her to the bathroom and put her on the toilet and all she keeps saying is that she wants a diaper.
Why is my kid suddenly wanting to be back in diapers?
Re: WTF is wrong w/ my daughter all of a sudden
Maybe give your daughter a 'job' to help with the baby - help her understand that she's still in the family, she's not being replaced, her role is just changing. Do you have a place for baby stuff - maybe a room? When she finds a diaper, maybe have her put that in the room for the baby. Perhaps try that if she "doesn't use the potty, who is going to show her little sibling how to?" Maybe have her "donate" some of her younger toys to the baby room, and then take her out and let her pick out a few older toys to replace them. That can help show her the transition.
a word of unsolicited advice - practice 'alone play' now. My SIL always said how much attention she gave to Alyson because she wouldn't be able to give it to her anymore, and she totally shot herself in the foot with it. Not only will she not play by herself now, but she throws a FIT when anyone wants to pay attention to her sister and not her now. She now associates the lack of constant attention with her sister, since it stopped when she was born. So now she uses the fits to get negative attention, instead of just less attention. Her sister is now 17 months old, and she's just NOW getting better about it.
Good luck!
