We use the bumpers and I was worried he would use them as a foot step now that he is almost 2 but the only thing that has happend is he has broken the ties and the bumper really does not provide that much of a step. Since the ties broke, I took it out and now, I am CONSTANTLY searching under the crib looking for his passifer that has fallen through the slates, needless to say, I am fixing the ties and putting it back in!!
