Foray into multigrains

I must have gone nuts. Dunno what overcame me at the health food store when I decided to pick up bags of wild rice, brown rice and wheat berries. Somehow I couldn't resist when the grains aisle beckoned to me.

I'm guessing it must have something to do with that multigrain rice that I tried for the first time from Ichiban Bento (ChangiCityPoint, new mall opposite Expo MRT). It was absolutely awesome - tender, fluffy and chewy, not like the boring white Jasmine rice that Chinese people like to eat everyday (at least here in Singapore). Ok perhaps it's better now that we've switched to Japonica Rice which is tastier, chewier and slightly sticky. But that multigrain rice, oh...

I've done some reading up on the net on how to cook the different types of rice, and I'm still figuring out how to cook them all together (including white rice because the kids will surely revolt if I don't ease it into their diet).

#1 Brown rice 1:2 50min
#2 Wild rice 1:2.5 50min
#3 Wheat berries 1:2.5 60min
#4 Quinoa 1:2 20min
#5 Jap white rice 1:1.2 20min

Ye gods. How to cook?? Perhaps cook the first three first then add the last 2 about half an hour later? Or cook #1 -3 together, #4 and 5 together then fold the finished product together? This doesn't sound viable. Anyone out there? Can give me some advice please??
