N.N.
I have a a 3 year old daughter who was potty trained at 28 months old(with the occassional accident)Not to long after and she went completely backwards and wanted nothing to do with it. I tried everything I could think of to try to get her to go back to using the potty (positive and negative) Why wouldn't she just go it wasn't such a hard thing to ask?But she wouldn't! Well I took the advise of a friend and tried just ignoring her.I put her in pull ups and did not ask her to use the potty and didn't make a issue out of her going potty in her pull ups. Low and behold eventually she dedcided (on her own) she would start going again.(She just turned 3 ) This is also the same advise my pediatrician gave me.I've been told the bigger deal you make of them not going on the potty the more attention they are getting for it and the longer it will take for them to start using the potty again. Almost every child regreses at some point. And even after they are potty trained will have the occassional accident.Hang in there .Hope this helps.Good luck
