What would a family of four need to survive for three months in a backyard bunker?

So pretend your four-person family is digging a bunker/shelter in a brush-filled canyon. The danger is unspecified; probably not nuclear. It's a warmish climate, with lows of 40F.
How large would the bunker have to be? What supplies would you need besides the obvious ones (Food, water, lights, batteries, sleeping bags, etc.)? How much food and water? I figure cooking would be a no-go, because of carbon monoxide. Any way around that?
How about toilet tips?
The digging would be secretive and extremely low-budget. How long would it take to dig without heavy machinery? How could you ensure the bunker's sturdiness without using metal or concrete? Wood and rocks are okay. Low-comfort is okay. What about air holes -- how many would you need? How would you block them in case of rain? How do bunkers protect their denizens from fallout while remaining breathable, anyway?
What else? I've done a ton of research myself, but I know you guys will come up with things I haven't even thought of. I would like the science and mechanics to be believable, but not necessarily error-proof. (Though I would like to know about the errors.) There is definitely a dose of insanity involved.
Yep, this is for a story.
