My 5 yr old ds has always needed very strict routine and never needed much sleep. I always suspected something was different with him and have embraced all of his uniqueness. He has now started making noises - first hey we're like spit the dog now he snorts like a pig a lot! He can't seem to help it and definitely does it more when stressed or upset. A first we tried ignoring it this may it worse, then we tried telling him off which also made it worse. He communicates well so I asked him why he does it he said it makes him feel happy but is upset when it upsets me. I'm convinced it is a form of stimming and am not sure what to do next do I meet with is teacher to see what she thinks? Or visit GP does anyone know he best route?
