My DD has had two accidents in the past two weeks. Is this a normal thing for a five year old? Nothing has really changed for her as far as her schedule. She goes iwth her dad saturday afternoon/evening and comes home on Monday after school. I spend as much time with her as possible, but I"m in school in the mornings and she is in Kindergarten in the afternoons. I'm just getting a little concerned. This seems to be a little out of character for her..
