baby proofing time!

We now have a crawler.  Well, he's taken two little "crawl steps" or whatever you would call them.  Last night he surprised us right before his bedtime with his exciting new trick.  All he has to do now is figure out that he's figured it out and he will be mobile.  A mobile baby is much more work, or so I'm told.  I'm sure it is - but I am still so thrilled with his new accomplishment that I really don't care.  We are now in the process of babyproofing.  Baby gate, check.  And that's it....  We gotta get outlet covers, toilet bowl clips, cabinet locks, and all of the wires behind the TV secured.  Anyone have any other suggestions?  Because we're gonna need 'em!
