My OH got home late last night after drinks with friends. He got a taxi home and this am forgot that his car was still parked at the station. I leave for work earlyish in the morning and he is responsible for taking the kids to school / holiday club most mornings. Today he suddenly realised his car was at station after I'd left for work so he gave the kids breakfast (DS is 7.5 and Dd is 5) and told them to be sensible and not go upstairs or open the door etc and that he had to go and fetch the car. He claims he legged it all the way and was back home in 8minutes.
I feel furious and sick with worry and unease. AIBU? I think they're too young to be left alone even for this short amount of time. I shared my concerns and husband said he sees my point of view but disagrees as he thinks the risks are minuscule. I've asked him not to do it again - at least until DS is competent at making a call on the landline should some problem arise. They are both very sensible children and I often leave them playing upstairs etc while I'm in the garden etc but they are always close enough to call me. Should I take this any further? Is this a safeguarding issue I need to be worrying about? I don't want to over react but I feel uncomfortable about his inability to guarantee it won't happen again.
Thanks for reading all this! Any sensible advice welcome.
