We toilet trained our ASD DD a pretty non-traditional route by reading no books whatsoever and following her lead/our instinct 😂 We were waiting for the traditional signs but they didn’t come so at about 2 years 10/11 months we got a potty and started sitting teddies on it for wees etc. We then went quite quickly to nappy free at home as much as possible and after a few wees on the floor she got the hang of that with gentle reassurance - but definitely lots of small wees to begin with. I think they almost cut themselves off as the sensation is strange/different. Or she was trying to get more chocolate buttons! Maybe the latter 🤣
She went backwards a little when we introduced pants in the house, and then later leggings/full clothes, but they were only small setbacks and she got the hang of it.
It was only at this stage we felt confident to go nappy free out and about, about four months in and 3y 3m. I think the problem is, DD is verbal but she doesn’t like to tell me when she needs a wee, and also hates to be asked/suggested - can cause a meltdown (even if she actually does needs one). She just likes to be able to go on her terms; which is hard if we are at the shops/park etc. This has improved but we still have issues in the car - it’s our last place to crack! She can hold it for two hours car journeys but then can wet herself and say nothing in a 5 mins trip from park 🤷🏼♀️
Poos were harder work - they really distressed her. She was a stand up poo-er in a nappy, and health visitor said that probably meant it was sensory related as squatting/sitting is easier but a more intense sensation. We were just super patient on this. She learned that she just had to bring us a nappy and that meant she needed a poo, and we let her poo in her nappy. When she needed to go I started taking her to the toilet so she could go in the bathroom, then we would take off the nappy and flush & say goodbye to poo (we read Poo Goes to Pooland 😅) She liked this routine so it continued for almost a year. Then I found Tom’s Toileting Triumph video and that really helped move things forward. She’s now been pooing happily and confidently (and telling me she needs to go, unlike wees!) on the toilet for a couple of months now and she’ll be four in September.
As you have a boy, Tom’s Toileting Triumph will be even more helpful to you I would
imagine - it covers weeing and pooing, couldn’t recommend enough.
