When do you decide to get help for your child by hiring a tutor? My sister is having a hard time with her kids who are in school right now. It kills me to see them struggle, but I don't want to interfere too much.
Well for a start, it has to come from her, not you. Really there isn't any particular time, it may come down to more what you can afford. In the meantime your sister could be working with the kids herself.
