shep, I think because she is still so young she will need constant reminders.
That was why I didn't push my dd to be potty trained until after 3 years old. I knew she would be old enough to know to go on her own without me reminding her at that age. (I know, call me lazy, it was easier to change her diaper!!)
Heck, my ds just got potty trained 2 months ago and he will be 4 on September 11th!!
2 down, and 1 more to go, although it will be a couple of years! lol
