I suspect that my almost 5 year old is on the ASD. He scripts a lot, doesn't communicate naturally and has issues regulating his emotions when he can't have something. He also doesn't have friends. We are currently trying to get somewhere with an assessment which is proving to be a long process. I'm wondering if he could also have PDA? He won't do anything unless it's on his terms even getting him to do simple things like brushing his teeth or come with me is hard work every day. On the other hand, if he asked for the TV and I said, no problem... first put your toys away, then take your shoes off and sit down on the sofa, he would jump at it. Same with the iPad. If I have the iPad in my hands, he's the most obedient kid in the world. He's severely independent. Doesn't ask for anything, he climbs everything or finds a way to get it himself. He's affectionate and always smiling. Can kids with PDA be effectively bribed? I know the methods that work for a child with PDA is different to a child with ASD so I'm afraid of using the wrong methods. Timeouts, stickers and rewards don't work.
