Along with this, my 2 year old daughter received an RV toy for her doll house for Christmas. One of the "features" of this RV is that it comes with a potty.
She also received a "grandpa" doll to go along with the "mommy", "daddy", "sister", "brother", and "grandma" dolls she already owns. The "grandpa" doll apparently has a few intestinal issues because he's spent a considerable amount of time on the potty, with the 2 year old shouting "grandpa is going potty" or "grandpa is going poopy"!
Whatever it takes to potty train her works for me! If that's a grandpa doll sitting on an RV potty, then so be it!
