To be fair, I also tried to potty train young.
Then I received advice from the health service that starting young can cause problems later on with continence, so to stop and wait for signs of readiness.
So we took a short hiatus.
Then the next bit of advice from the health service was "why are you wanting for signs of readiness? You just need routine" so we followed that and it didn't work. We were consistent to the T. It caused so much stress.
Then when we found out my son was autistic they recommended we speak to ERIC. I did and also did their webinar and everything that was said was contradictory.
Don't wait until signs of readiness, go to a routine, unless a routine causes apprehension and then wait for signs of readiness. Always change your child's nappy in the bathroom so they can associate the bathroom with toileting, except if the bathroom is a sensory nightmare for your child and then don't as it will cause trauma. Just get rid of nappies completely because they wick too much wee away for your child to notice, with the exception of if your child gets extremely distressed by being wet as crisis point isn't going to teach them anything. Never let them poo in a nappy unless they will only poo in a nappy and then allow them to poo in a nappy until they're showing signs of readiness. Always tell your child what to do unless your child has a PDA profile and then telling them what do do will just cause anxiety.
The stuff they were saying was all common sense stuff but didn't actually help us SEN parents or parents who's children were still not toilet trained by age 5. It just offered more confusion.
So between the NHS switching up their advice in what felt like an overnight 180, it feels like you can't get consistent support externally either.
