Last night I put my 5 month old ds in a gmd snapless workhorse for overnight. I had boingoed the two tabs together thinking that would be more comfy for him. In the morning when I was taking off the wool soaker I was horrified to find that in all his tossing and turning he somehow had shifted the diaper out from under the boingo and it was sitting on his tummy with the diaper off in no where. I was so scared and gingerly picked up the boingo and there wasn't a scratch on him! I have no idea how long it had been that way but he is in the squirmy roll over constantly stage and so I think it could have been against his skin for awhile. I was really happy to see that the boingo didn't mar him up. I guess I will be pinning at night though from now on!
