M.Q.
Our pediatrician once told us "If you start potty training at age 2, your kids will be trained at age 3. If you start potty training at age 3, your kids will be trained at age 3." Her point- most kids aren't really ready for it until age 3 (there are exceptions, and I am sure every single one of them will post here to dispute me). Anyway, we did not start potty training any of our kids until age 3- even when they showed an interest. If they showed an interest earlier, we would go with it and let them sit on the pot, etc. But, there was no formal incentive plan in palce until age 3. The result for us, failry easy potty training for all kids so far (one to go). I am not guaranteeing this, just offering one example. Just remember- you don't see kindergartners in diapers- it will happen.
