S.F.
My eldest son was autistic. He potty trained many years ago, but thought I'd mention what we did... he was good to go by 2 1/2. I first started using the potty at home and left the door open with his potty seat nearby so he could get used to the idea. Then I had him sit on it when he woke up and before bath like any other routine. I never pushed (autistics hate that and regress), let him basically train himself. I also bought a Barbie brand Kelly doll that had a potty/ sink set. He loved it. I had a lot of teasing, but hey, I could care less! In fact, I am in the middle of kid #4 training, and let her go at her pace as well. So far, so good!
