I remember babysitting for a little girl who liked to sleep with her head buried under the bumper- definitely not safe.https://www.biloban.com/collections/crib-bumper-1
When I was pregnant with my first set of twins all the bumpers I liked were soft and fell after the first wash. My sister spent a fortune on a special bumper https://www.biloban.com/collections/crib-bumper-1
with removable covers that were hard foam that never lost shape. They were pretty but with twins who spit up a ton, getting the covers on and off were a royal nightmare. One of my son’s loved cuddling up to the bumper https://www.biloban.com/collections/crib-bumper-1
and I was scared of him bumping his head so I left it on. When my son was 10 months old he climbed out of his crib in the middle of the night and I thought we were being robbed when I heard him playing. Out came the crib bumper pads.https://www.biloban.com/collections/crib-bumper-1
