Its her problem to get her child to school. If you went on holiday 1 week before the holidays would her child her not go to school for that week? You cant be held responsible for her child getting to school she is. She is also responsible for picking her child up. Also it sounds like your children are older than her child - your children are already at that school - so what happens if you dont move and you stay were you are does she expect you to take and pick up her child even after theyve left that school? I would tell her to find her own way to and from school that she cant depend on you being there.
