Once a week Dh does the school and nursery pick up for ds3 (2) and ds2 (8.5). He brings ds2 home where ds1(12) has already arrived after getting the bus. About half an hour later her goes for ds3 to nursery and has, on the last two occasions, left the older two at home. Nursery is about a 10 minute round trip drive if there is no traffic but it is a busy road and can take up to half an hour. He also on the last occasion called into a shop so was away about 3/4 of an hour.
I have no problem leaving ds1 for that amount of time but I feel ds2 is too young. However, as dh points out, they are both sensible, they don't fight and we have lots of good neighbours they could call on in an emergency. He is also available on his mobile the whole time.
I'm being unreasonable and over-protective aren't I?
