building a team of siblings!

[Sago]

sibling rivalry is driving me mad at the moment - it is mostly between the eldest two girls (7 and 5) but starting a bit with youngest son (just turned 2).
I have been trying to think of things they can play together but most games seem to be competitive ie, players against each other. Do I need to get in a management consultant to create those team-building scenarios (like build a craft out of three matches and sail down the amazon on it) ?
No seriously. Any ideas of games that will make them play together? Any books?
Thanks!

Always reckon that years of dealing with sibling rivalry more than qualifies any mother to a top diplomatic job at the UN.

It's difficult. Would they build a camp together under the table or play shops or something?

ah, FernieB you won´t believe it but between posting this am and now, I have been for a job interview at a UN agency!!!!!I made a real mess of it so must encourage my children to keep on fighting so I can build on my experience!
i´ll try the camp thing, the shops always ends in a fight as the eldest want to be in control all the time...perhaps that is the issue I should be addressing!

Couple of things that mine like (though am world's crappest teambuilding parent in general):
Funny Sentences -- where you say just one word each in turn (as in I'm Sorry I haven't A Clue, if you're a radio fan). One of mine always gets the word Cupboard into it somewhere, which the others find bizarrely entertaining. Useful for boring car journey and mealtimes.

Follow My Leader -- with turns. You could be the one shouting 'Change!' at intervals, if you can be bothered.

Standing at either end of a Slinky or skipping rope, wiggling it madly.

Errm... that's about it. Oh dear.

thanks Lancelottie! I am also laughing at the thought of putting cupboard into every sentence! I will definitly give them a try.......they do sometimes play nurseries quite nicely together but it`s always the eldest as a member of staff and the middle one has to do as she is told, poor thing!

My dc sound rather like yours, and similar ages too. A friend has this cooperative board game which works quite well, as they have to work together to get a good result. It makes them think a bit differently...
