Hi, my son is 25 months has been potty training for 3 weeks now, and he's really good when we are at home. Before we leave the house, I put a diaper on him and Im so amazed as to how long he has learned to hold his urine.
We started potty training when we had hot weather. We started using the underwears right away, I never used pull ups because I believe that it can confuse them. So I talked to him about how he was becoming a big boy and that we shoild start using the big boy potty. That whenever he felt the urge to go, to let me know or come running to the potty. Its ok if you dont make it on time, accidents happens and we are just learning to use this. Now the whole time I was talking to him, I was looking into his eyes. We started with m&ms' 1 for pee and 2 for poop. After he finally got the hang of it, instead of treats, I applaud him, danced and tell him straight in the eye that I was very proud of him ,and that he was becoming a big boy just like Caillou. And sometimes Put some youtube videos of kids using the potty just like him. I think almst every kid, love that great attention of their parents, specially to tell him that he's doing a great job. And sometimes he'll ask me for a treat but I tell him that we dont have any more but that Im extremely happy for him and throw him in the air, and let me tell you that he prefers that than a candy.
Conclusion, talk to him, have eye contact with him, but most important thing of all, make sure that YOU feel confident in him and that YOU feel happy for him. Because as you know, kids sense evrything from you.
Good luck and maybe stop using the pull ups, and maybe l let him be wet for a bit, maybe he'll learn that he doesnt like that feeling. If you do that, ask him how he feels, and hoping that he'll say "uncomfortable" than explain to him the reason why we need to run to the potty when our brain tells us to. Tell him that you were just like thT when u were a kid and felt very cold too....etc...
