Hmm, I never thought of bungee cords to tie my chairs!
I have my dgds overnight quite a few nights a week. I have a portable playyard/crib thingie for a crib. We never had any problems with the now 2 1/2 yr old but the 16 mo old, forget it! We found her out of it a few weeks ago and couldn't figure out how she managed it until I watched her the other day - she actually put one foot at the top and used that leg to help pull herself up and then dropped over the side!! I have 4 of my own that were all mischief makers but she tops anything they ever did! I told my dd she is the payback baby!
