DS is five in May and autistic. He was a bottle-refusnik and has serious food and gastric issues. BF was a godsend in the respect of continuing to bond with him / comfort him when he regressed and wouldn't even make eye-contact with me. Also, autistic children do get obsessive and rigid in their routines < justifies self> 
We have made progress in that for the last couple of years he knows that BF is not needed outside of the house. In the last year, not during the day at home. DH has been a star at night and has been sleeping with him in order to break the habit and now he just comes in to see me in the morning for a quick nip.
Lately it has been a nipping action and a bit painful. He is too young to be losing baby teeth but I wondered if his adult teeth are shifting beneath and changing the shape of his jaw or whether he is just forgetting how to latch? He has started school full-time but I doubt this would have any impact in terms of peers. If he cared what other people thought or did he wouldn't be autistic.
TIA
