No TV till homework is done works for my 7 year old. The 3 year old has no homework.
The rule at home is simple: TV after homework. My 7 year old accepts it, mostly. The 3 year old has no homework, so as far as she's concerned TV is available from the moment she gets home. So at 5 pm the little one is watching cartoons and the elder one is at the dining table doing sums, hearing every cartoon and telling me it's unfair. She's not wrong. I don't want to invent fake homework for a 3 year old. I also don't want to switch off the small one's TV just because her sister has work. How do people keep rules fair when the kids are at completely different stages?
