And the potty training continues....

So potty training has still been a SLOW ongoing process in our household. We have run into a major speed bump at the moment. She still manages to tell us every time she has to pee or poop but she has been very stubborn about actually going in the potty chair. She willingly goes into the bathroom and actually loves to sit on the potty chair "reading" her books, but she just refuses to go #1 or #2 in it. She really has excellent bladder control and will hold it even though she has to go.  So to try &  fix this she has been wearing her very cool disney and dora the explorer underwear during the day when we are at home. She's learned that we are not supposed to pee or poop in our underwear or on the floor which has created a major dilemma for her-- (Can't go on the floor in my underwear and don't want to go in the potty). When she has to pee she will run up to me and say "No peepee on floor....no peepee on floor" in this really urgent way and I tell her lets go to the bathroom and she says "No bathroom..... no bathroom!". UGH!!!! She eventually ends up with wet underwear and she says "Uh-oh, all wet". No Kidding. So the question now is how do we get munchkin to actually go in the chair???
