. . .but once it's done, you don't have to do much else!
Fortunately for us, we had already rabbit-proofed our home (sounds crazy, I know, but all you need is one elctrified bunny. . .) which meant we didn't have much more to do.
You've probably already done all this, but just in case you haven't: make sure your outlets are covered, doors that are going to be left open have rubber stoppers to prevent pinched fingers, anything you don't want touched moved up high, table/fireplace corners are protected with foam strips or padding, toilet seat has a lock, cabinets have latches and doors are kept closed. If you're in a major city you can probably find a baby proofer in the yellow pages. They come, do an estimate of your home and then do all the work for you. Of course, you pay for it!
If you want to do it yourself (we did!), most large multi-purpose stores will have what you need to get started (Target, Wal-Mart, Babies R Us), etc. Then if you can get someone to watch your kid for an afternoon and plan for both of you to work on it, you can do all the installation at once. Then just keep a sharp eye out on your kid to make sure you didn't miss something. One great thing we got: an entertainment center from IKEA where the shelves for VCR/DVD/Stereo etc. are above the TV. No magnetic doors, no sliding doors, no glass doors to clean, but everything is out of baby's way!
