Need some advice, im a father to a 4 year old Autistic child and for the past few months he acts like a dog, even attempts to drink out of the dogs water bowl which will make him sick. Recently he has started weeing and pooing on the floor even though he knows he has to use the toilet and, even though he recognises what he has done and that its naughty, he still does it. Anyone else been in a situation like this? Is it a phase that will pass naturally or did you have to actually help them get out of it?
