Please can you help? My 2 daughters aged 6 and 4 will not tidy up without a major tantrum. We have tried making it a game, shouting, reward charts, just ignoring it, confiscating toys,discussing why we would like them to do it and doing it with them. My husband and I are at the end of our tether. We think that they are old enough to accept some responsibility for looking after their things. Where are we going wrong?
