My husband and I tried everything - he goes pee in the toilet not problems but refused to go potty in the toilet at all -we tried sticker as reward, read book,etc .. but he doesnt have any problem in messing his pants.. he said he doesnt know why he does it.. he doesnt even mind it seems. When he was a baby was constantly constipated it. One time he sat in the toilet to please us to try to go poo & he was crying while going poo in the toilet like it was hurting but he was not constipated it. so he doesnt try anymore in the toilet he just does it on his pant constantly.. he does knows when he has to go j poo he just choose to do it in his pants..he is a real sweet child we are planning to take him to a psycologist..as a baby he was treated it for Apriaxa .. I dont know if that would have to do with that or not. I asked him does it hurt when he goes into his pants he said no. If anybody has any suggestion please help us we are running out of ideas. would this be a development delay issued? please help..
