Hi S.,
You have a lot of great ideas here from the other moms. Remember to check in with your reaction to the ideas, though, to choose what suits your parenting style and your son's personality.
As a mother of three and a Parent coach, I, too have advice.
We regularly post on this issue because it is an important milestone. It can be challenging and drawn out if you force the training when your son is not physically aware of his urges (prior to the event) or when he is not willing to do it.
On the other hand, it can be a positive, short-lived process that is very successful WHEN the conditions are right. Check out my responses and the responses of other moms to other potty training questions here on Mamasource for more ideas.
I highly recommend books for you and your child. We used Once Upon a Potty and liked it. Although I have not read it, the other book (Potty Training in Less Than a Day)sounds good, too. Make sure, though, that any book you read talks about watching for signs that your son is ready for this. When he is, it should go easily and smoothly.
Let me know what you decide to do!
J. B.
Parent Coach
