Shadow Wizard gives good advice. I will add tho that, more generically, you have every opportunity to control their world. You can make it small with baby gates, and filter the stuff that's in that area.
If you gate off the living room (which is usually the simplest) just make sure you don't leave normally adult things laying around... like drinks. oh yes, they'll get it. Remote, magazines, dvd cases, cigarette packs, shoes, pets, they're going to stick it all in their mouths. as long as you filtered it well, you can be reasonably certain they're not going to do any damage while not having to be horribly restrictive.
Oh btw... go get a cheap, colorful, universal remote from target. leave the batteries out and give it to them. It won't take long for them to know which is theirs.
