I lead parenting seminars and one is called Potty 101 so this is one of the areas I do happen to know a lot about. I will tell you that I like best what one expert says when she writes, "You wouldn't expect your child to learn to read in one day would you? No! It's a process... and so it is with potty learning." Boys typically are not completely day "trained" until they are 3 or after 3 on average. You are right at the point of the process of encouraging him, modeling for him, enticing him with fun books and little toys that are only to be played with while on the potty (a potty basket to be brought down off the shelf for sitting and relaxing on the potty). Potty learning should never be an event that evokes anger or overt frustration but rather should be approached with the realization that once they are physically ready, then it's their choice. You can entice, encourage, cajole all you want but ultimately it must be his choice and this is a good thing. There are only two things children truly have control over in their little lives as they are realizing developmentally they are their own entities separate from Mom....What they put IN their bodies and what comes OUT of their bodies. So, give him lots of "important jobs" at home so he feels powerful and needed, (that are age appropriate like folding wash cloths, sorting forks and spoons, stacking books, etc) and always give him choices with limited options: "Which do you choose? The blue shirt or the green shirt?" Allow him an opportunity to do as many things independently as possible. Get a little stool in the kitchen and put the plastic cups within his reach. Provide his own little shelf with his name on a piece of tape marking it as his in the pantry and the fridge with snacks and drinks he can open himself. Believe it or not, all these independence tricks will help with pottying. And remember, accidents and mistakes are how we all learn, so when he wets his pants, smile and have him help you do the laundry and clean himself up in a positive manner. I am a counselor for parents in Marietta and Kennesaw as well as for young children ages 2-5. If I can be of further help, just drop me a line! good luck!
