When both our children was in daycare somewhere between the age 1-2, we told them that he (both times) was almost potty trained, but still need a diaper to sleep. They wanted to just give them a diaper and told us "oh, but boys get out of the diaper later". No lady, he is well aware of when he needs to go, and we've trained this. Now work with us, rather than destroy our work. No wonder some of them get our of the diaper so late, when the professionals care takers have so little time that they recommend later potty training.
