Potty update

Yes we have something to update potty wise. Last week Anna Lena had diarrhea so I took that as an opportunity to teach her the word poo poo. Well now three days, yes 3 days in a row, she has pulled her pants either up or down and said poo poo. Then after being seated on the potty poos and pees. We follow with our poo poo dance and chocolate (the boys are very supportive at this point).  Now I'm not ready for potty training yet but I like seeing her sit on the toilet.  But how do I teach her to stop lifting her shirt to pee?
