My daughter is starting playgroup soon, 3 mornings a week. It's only 2 hours but she's just potting trained and still has occasionally accidents when she's distracted. Do I just let her go and the staff do what needs to be done, or should I put a pull up on to prevent her being wet? She hates it when she wets herself and don't want her to be embarrassed but also don't want her to get confused!
