I've a hospital appointment come through, for exact time DC leave house to go to school. I need to leave at the absolute very latest 45 minutes before. DH reckons DC can get themselves out to school and thinks I'm babying them by saying I'd try to shift the appointment and if I can't beg a favour off someone. They are 7&9 and we live next door to school. They do not need to walk on a road or even pavement to get there. I think they're too young and will lose the key He thinks they'll manage. DH can't stay in the morning as he's leaving early from work to be there for a parents meeting in the evening.
