S.H.
I believe that pull-ups are the death of real potty-training. As a daycare provider, I always request thick training pants & rubber protectors. The parents almost always balk at this....but the ones who comply have kids who are trained in 1/2 the time. Been doing this for years now....hate pull-ups! I truly believe they delay the process & become a crutch.
Therefore, get rid of the pull-ups!
