At the moment, we're trying to find the money for hot water in our home, and to repair our leaking roof. Private school is not an option at all.
As for complaining to the school, I don't have a chance there. I have enough trouble getting them to acknowledge the fact that there is a head lice problem. Trying to change the teaching methods would be futile. The rest of the schools nearby are just as bad or worse.
I can't consider home schooling either as my husband and I both work to pay the bills.
Life is pretty rubbish right now, but we're trying to repair our home, save some money and move. In the mean time, we're doing the best we can at home to reverse the effects the school is having. It might not be good enough, but it's all we can manage right now.
