My ds is 3,5 and although highly intelligent we have him potty trained although he wasn't interested in it, he has now gone backwards for whart reasons we can't fathom, but its only at school he will speak to the children but not the adults and there fore won't tell them when he needs to go he goes 4 days a week its not the fact he hates school he lives fo it can't wait to go he knows he has to tell them but has told me he is refusing to talk to them when I ask why he says I'm not speaking and that's that! He is very stuborn and knows its wrong not to tell them, he won't do a number 2 in the loo either he goes and hides in the corner whn I take him to the loo he just cries and then gets constipated as he will refude to go, I have tride bribrary etc treats u name it nothing works, he has his quirks which my mum has finally admitted that he might have a syndrome or sumthing, but I feel like I have failed as a mum as he's not at all like his friends, I'm at my wits end and now getting quite embarassed when I collect my son and I'm the only one hnded a bag of wet clothes.I dnt want him diagnosed with sumthing but I do as everything will have a reason, there are things that make me thing autism but not everything fits I just need someone who's been through this to tell me there is a turning point for this, my mums saying is your brother was like this he won't be doing it when he's 10! Grrrrr
