I haven't used them but they came with my set so I have them. The last couple of weeks DS has been spinning in circles in his crib. His new thing now is sticking his feet on the rails and trying to push off them and roll over. Sometimes I catch him with his feet in between the rails. Doors your LO do this? What do you do?
Re: Bumpers?
We have the breathable bumpers (I ended up cutting up parts of the other bumpers to add decor to his room, lol!). He does like to put his feet on the rails, play with the bumper with his feet &, if we didn't have the bumper, would definitely have limbs sticking out!
I actually just bought the BB for my IL's house. They bought a small wooden portable crib for when he's over there. Last Saturday (family get-together night) he was up there asleep & then suddenly started screaming. I ran upstairs & he had moved in his sleep & got his arm stuck through the rails

same here!! Bumpers are ok.. I use them...they are breathable... break a childs arm? come on...
