Potty train - DAY 4

We had a mistake she went to bathroom then came back and asked me to come with her and then it was too late.  After I gave her a bath she was on the phone with Josh I asked her to tell daddy what happened.  As she is looking at me she says I peed MOM.  The pee down her leg.  I get upset but feel bad because some kids wouldn't even train this easy.  I am very luck with this girl.
