Can't decide if this is a reasonable worry or not. I have 3 teenagers (13-17). Next week my husband flies back from a business trip while I fly out on one. there is a 3 hour gap (during school hours) when we are both in the air. But for those 3 hours, we cannot be contacted so if there was an emergency or anything, we aren't around. We have no relatives close by - the closest is a 4 hour drive away. I can ask a friend if I can give her name/number to the school just in case. Am I overthinking this? Would you worry about an accident in school etc.
