Wow.. that’s tough. My guidelines are the same as yours.. I think your decisions are very sound. But I think if your parents still don’t want to listen to your requirements, you’ll need to put your foot down, and let them know that if they can’t manage to entertain her using other means (eg. Reading/non digital toys) and if they are unable to provide healthier snacks (eg. Fruit), then they cannot look after your girl anymore, and you’ll let the child care centre know that the grandparents are not allowed to pick her up from school. Of course, that’s the last resort. If you can, see if you can work with them to show them how to engage your girl with other things (a lot of the time, they don’t have the confidence, and need you to demonstrate it), and you can also work with your mum to prepare healthy snacks for her.. when they feel accomplished, they’re more likely to be willing to try:)
