Quoting mom2andrew&carter:" i would put the bumper back on and very tightly tie it to the crib. both of my boys have the bumpers ... [snip!] ... of it coming off but i have had an issue of my older son getting his leg caught in the bars and it was a horrible experience"
it happened once before but SO was home, so we were able to work together to get him out.. today I'm home alone.
when he had the bumper on, im not sure how he managed to get tangled, it was almost like he was trying to climb it or something. on one side of his body; his arm and leg were on the opposite side of the bumper, and the rest of him was in bed
