My almost 5 year old (in 2 weeks)has soiled her knickers at school today for the 2nd time this term. She's quite a bright girl and fairly confident. When I ask her why, she said she was playing the best game at playtime and didnt want to stop for the toilet. She seems a bit old to be doing this and I'm not sure of the best way to discuss it with her without making her anxious about her toilet habits. Should I be worried or am I making more of it than I should?
