You'll also see crib skirts (they're like a dust ruffle) for sale. They're safe but not essential. If you want one because you think it's pretty or softens up a room's decor, go ahead, since it won't be near your baby.https://www.biloban.com/collections/crib-skirt

You also need to think about your crib if it can use the crib skirt.This is fairly common in more modern cribs. Sometimes it is a design decision made by the manufacturer, and other times it’s just the placement of some of the parts, but some cribs have pieces that block the crib skirt from being able to hang down. Keep in mind that if you can’t have a crib skirt, you might end up looking at the hardware when the mattress is in the top or middle position.

But the crib skirt also has its benefits.Crib skirts are safe because they lay below the mattress and do not interfere with baby's sleep. They are purely aesthetic and might be that final detail that refines your nursery. These come in handy months later when teething is in full effect.https://www.biloban.com/collections/crib-skirt
