Hi Marty-
We haven't bolted our furniture to the wall, but certainly if you've got tippy bookshelves, it may be wise to do so...
There are some outlet covers that are supposed to have sliding doors and are easier to use, so I hear,...I've just got the plain plastic ones...I suppose none of them are going to be fun w/arthritis, tho...
It's so hard to tell you what babyproofing you will need. I tend to teach my LO what not to touch and why. He was an early walker at 8 mos and soooo much stuff was in his reach and he was soooooooooooo persistant, it just became easier to have cabinets full of stuff on his level that he can mess with...
