Let's hope it is not too serious op and it is successful. I think the main point about her staying in hospital is that she has three young children It is hard to rest at home with them that is why she should be allowed respite from that responsibility. for instance when I had four hour op for cancer and was sent home the next day (to no-one) the best help was that my daughter looked after my dogs. You can't afford any responsibility when you are recovering. That's why it's best she is in the clinic and can just concentrate on herself. It's hard for mothers of young children not to put them first.
Bereavement wipes out everything
