DD has just turned 8. She gets showers on her own and I wait outside the bathroom, but I still worry about baths. She wants to use her new bath bombs so is asking for baths more often and I feel like she's old enough to be in there on her own but then I worry about how easily drowning can happen. She can swim ok but I don't think that matters in a bath. What age did you leave your kids alone in the bath? Just want to get an idea of what everyone else thinks is acceptable to see if I'm being too over protective.
