My son is 4 and I am potty training him. It is a complete nightmare. He won't tell me when he needs it . If I don't take him after a certain amount of time, he will just do it . The number 2 he will not do on toilet no matter how many times I take him. He will do it in his trousers or pull up. He is starting school in September and I am worried . He has Agenisis of the corpus collosum and I feel like he has Autism and Adhd which needs to be diagnosed. Any advice from mom's who have been through the same?
