I think 2 1/2 is young, especially for a boy and with possible adhd. Adhd'ers are behind in maturity.
Do you suspect sensory integration? Do you know what it is?
My son was 100% trained by age 5, but then we dealt with his hyperfocusing and he would pee his pants.
It also took me putting my foot down. He was trained with peeing sooner than the pooping, this took longer.
Again, I think 2 1/2 is still young but it doesnt hurt to start "teaching".
Boys are also later than girls, and then you add the possible adhd to the mix.
BETHANN40255.1105208333It's more of an assessment than a test. The OT at the school assessed my son with ADHD, but you could look into Child Find (or the equivalent where you are). They deal with placing kids in the 0-3yr bracket for developmental delays. The group in our town is fantastic. BUT, you have to seek them out. They aren't really allowed to approach you and ask if you want your kid to be assessed.My son qualified here in Massachusetts for Early Intervention due to his speech delay. They diagnosed the sensory intergration. They also placed my son in a integrated preschool so he would continue services. (unfortunately the school didn't but that is another story)
At our integrated preschool it is NOT required for the children to be potty trained. It is a mix of children needing services like speech, OT, PT. There were autistic, down syndrome, etc. but also children there who needed no services and the cost was less for their parents. It was also a preschool where children would NEVER be expelled from. Most states have them.
My son played with anyone who would play with him, his speech was horrible but the kids understood him and it did work.
Your pediatrician should know about sensory integration but google it when you have a moment. Please ask any questions.
Also if you need services for sensory, which would be a Occupational therapists, your insurance will cover visits.
Again please ask any questions!! My son is 12, turning 13 in June and he has speech delay, sensory integration and adHHHHHHHHHHHHHHHHHd. 
Hi,
DS potty trained at 3 years & 3 months. Boys tend to be later ...with the extra equipment. I tried him a couple of time before then (in 3 month increments) but knew quickly it wasn't going to work. Finally, he decided for himself..and potty trained in one day (pee and poop both). I suspect the best bet is to relax a bit with him and wait for some really potty training signals.. Good luck.
My son also has sensory integration disorder (and ADHD) and he potty trained late- 3yrs 9mos. We tried all of the tricks- candy, no diapers, only real underwear, put the potty in the living room etc. NONE of them had any effect! He did it when HE was ready and not a day sooner. One day he just started going on the toilet all by himself and has done it ever since! If I had known what I know now I would have just relaxed and let it come naturally. We like to think we are in control of when they potty train...but really we're not!
He will do it when HE'S ready and not before
so don't beat yourself up about it. You don't deserve that!
Good luck! I was feeling kind of pressured here to potty train him because he has to be potty trained to start school and the specialists are telling me to start him in school this year when he turns 3 and he has to be potty trained to start school. I never heard of sensory integration. Looked it up when I read your post and we are seeing his pediatrician next week and was going to ask for a hearing test because of his speech delay and when he does say some words it sounds just like a deaf person speaking and he also pays alot of attention to my lips when I talk to him. Will also ask about the sensory integration. How do you test for that?
Ditto to most of the above posts! Our little guy (adhd and pdd-nos) was 4 yrs and 2 mths. And we also tried every trick in the book, but he did it when he was ready. At one point, I was setting the kitchen timer for every 15 minutes and would bring him in the bathroom each time...talk about a looonnngg day! Dr. Phil had a show on not too long ago about kids' issues , including potty training. I forget the specifics, but it was basically about "modeling" a doll's behavior (one of those that you can put water in and it wets). Anyway, it might be on his website still, and he guarantees it will work in days..although he's never met some of our kids, right!
As for the school not accepting nontrained kids, is this a public school preschool? I know ours here in MD did make an exception for kids that had a diagnosis since this is SO common with our kids. They were even going to let him start kindergarten without being trained if needed. I know there were some preschool summer camps here that wouldn't take kids if they weren't trained by 3, but I always felt that was a form of discrimination due to their disability. But, then again, I wouldn't want him in a school that didn't want him!
Thanks so much to everyone for all your help. It's a public school preschool. Except for expensive private schools that is the only option here. I had a very hard time finding a mother's day out program that would take him but found him one finally and he starts next week.
I agree about the school issue. If the child has a diagnosis then the school should be able to take him not potty trained. My son started public Pre K preschool at 3 yrs old and they said because of his diagnosis and IEP he didn't have to be potty trained.
Also, just for what it's worth...my son's pediatrician told me (even before we knew about my son's "issues") that she doesn't recommend even STARTING to try potty training boys until 30-36 months. She said it's like beating your head against a wall if you don't wait until they're ready!
