Oh, GAWD, I don't even know what to do with this thread.... Hahahaha. I am half laughing and half shuddering at the thought.
This is the reason that I never let my kids sleep in just a diaper, lol. I heard these horror stories when my oldest was a tiny baby. And luckily they never clued into taking the pants off while in the crib. Praying the smallest baby doesn't figure it out, either!!
I have also heard of the backwards onesie idea. Taping the diaper is a great idea. I recommend clear hockey tape ("sock" tape). I use that s#@* on EVERYTHING. It's my version of Red Green's "duct" tape. (or is it "duck"?)
I can't get over the fact that they BOTH did it today..... crazy.
