Is HE ready? If he's not ready, you could be up for a battle.
If he is ready have A LOT of patience. Also, with your move he could very well backslide.
Our son is 5 and was dry through the night very early. But day time wetting is still sometimes a challenge they get very busy and don't want to stop playing to go potty.`
Use pull-ups, they are very helpful, also have him help pick out his 'Big Boy' underpants, that is always very exciting.
Figure out a reward system:
ex:(Create a sticker chart)
Sitting on the potty (w/ no production) get's a sticker.
Sitting on the potty and peeing so many times (# determined by you) gets a favorite snack.
Sitting on the potty (# of times) and poops gets a______. Whatever is valuable to him or your family.
If he's ready it could go very quickly, you'll have to adjust your rewards accordingly. ALWAYS carry extra clothes, wipes, underpants pull-ups and a plastic bag to put the 'OOPs' into.
Oh, and kids love public bathrooms, makes us cringe, but if they have to 'go' take them in.
Always take him potty before you leave the house on a short trip here and there. Take note of where you can take him potty ( stores, restaurants etc)in public.
Technique:
Usually easier for them to sit to start with. When you're ready have him graduate to standing. They need help with their aim...while sitting it could shoot out between the seat and rim and while standing, well give him a tp square to shoot in the water, some people say Cheerios but they really don't flush very well. Be prepared to do a lot of wiping up!
Have Patience! Good Luck!!
Like the other mom's said if he's ready go ahead, w/ your move he may very well regress. But don't force it, you really do wan this to be a positive experience.
