My son is a very talll 3 year old. He has Autism too. Doesn’t eat well so I give him a bottle full of milk before bed so I know he’s not starving overnight/waking up hungry. I had a problem with him peeing through diapers. I’ve tried different sizes and brands. Ultimately what worked for night was overnight “underwear” I thought it wouldn’t hold pee with the word underwear but I was wrong. It has put my mind to ease knowing he isn’t soaked throughout the night. I’m trying to potty train him as well. It’s hard as I have a needy 4 month old but he knows when he needs to pee. I’ve even gotten him to finish pooping on the toilet. It definitely is hard as I feel like I need to be way more consistent. I just want him to be potty trained before he goes to school in September 🤞🏾
Having experienced potty training with my asd son I didn’t bother waiting with my pre verbal daughter and started age 2. Basically I put her on the toilet/potty every time she looked busy. We used actions like patting our bottom (there is a makaton one) and recognised her noises. By the time we took away the pull-ups it was a lot easier as she understood. My son was repetitively taking him and removing the nappies. Took months for him to realise. We were effectively catching it.

I started potty training my son at 18m due to him being on the spectrum, it took till he was 3 to master it, I started off with having the potty in the room and encouraging him to sit on it clothed, then I moved to sitting him on it during nappy changes, so that he gets used to the feeling of sitting on it without clothes on, i then moved onto taking his nappy off and asking him every 30 mins if he needed a wee, I gradually increased the time I asked him. It may help getting her to use a toilet design potty as well and visual aids, along with sticker charts :)
