Moaning spoilt kids - help !

I have two boys aged 8 and 6. All they do is moan. They are quite spoilt really. My husband is absolutley brilliant with them both. They both have season tickets for the football, they go to karate twice a week, swimming lessons, play football twice a week for a team. My husband plays football in the garden with them every night for at least half a hour.

When it comes to saturdays and sundays they expect to be entertained, taken out etc. They get to go to the cinema and bowling most weeks. We also have a caravan that we try to get away in,

After being taken to the Cinema this morning they have both really moaned and played it up - wanting to know what we are doing this afternoon. So they didnt get took to mac donalds and we have told them we are staying in all afternoon. Lots of tears later . . . . .

Has anyone got any advice for me ??? To get them out of this moaning spoilt stage. Perhaps we have to be a bit harder on them.

Im going to sit them down later and try to have a chat.

I dont want them to turn into spoilt brats.

Thanks

Michelle
