For the past few days, my 21 month old insists on getting on the potty every time I change her diaper. We read books and she sits there for a long time with no results. Is she telling me she is ready or is this just a passing phase?
As far as Dr. Sears readiness check off...

Imitates your toileting
Verbally communicates other sensations, such as hunger
Understands simple requests, such as "go get ball"
Begins to pull diapers off when wet or soiled, or comes to tell you he's dirty
Follows you to the bathroom
Able to pull clothes off
Climbs onto the potty-chair or toilet
Has dry spells: stays dry at least three hours
Investigates his or her body equipment

She is doing everything except having a dry diaper for 3 hours, I'd say that is more like 1 hour. I don't want her to get set up with the wrong signals or burn her out on the potty.
Thanks for your opinions :-)
