My kids are 5, 9 and 11. The 11 year old is often left in house by himself for 1-2 hours. He’s very responsible. He also goes to the park etc independently and walks to school by himself.
The 9 year old will be left with the 11 year old occasionally but only for 15/20 mins. And I don’t consider that the 11 year old is in charge of her - she’s looking after herself in those instances.
How old would be ok for the two oldest to jointly babysit the youngest? 13/11/7…14/12/8?
