Hi L.,
Of course, every child is different. I think it is fabulous that, at 26 months, your little guy will go when you take him. That is really young to have mastered that. Yeah for you both! I would suggest that you continue doing that and just be patient with him and one day he will surprise you by telling you that he has to go. There's no telling how long it will take.
My kids were each vastly different with one totally trained at about 26 months, another not until after 3 and the last not until 4! My grandson is 4 and just (finally!) started telling us when he needs to go. We try to be very patient with him because he seems traumatized when he has an accident. We let him know that it is ok and that he will do better next time and he does. Once he was totally ready, it only took about a week. A couple of times my daughter got angry at him when he peed on the floor and he got really upset. I told her that she should not get angry with him because he is just learning and it just seems like the potty issue is so huge for the little ones. When she was patient and positive about it, he got it right away.
I don't know if you are using pull ups but I just wanted to mention that they seemed to slow the process down for us. They feel too much like a diaper, I think. When we just put him in "big boys", he did much better.
Anyway, nice job so far!
L.
