The Just Born "Botanica" Fresh Air Crib Liner, the crib bumper alternative, is safer and easier to use than any other bumper alternative. The Fresh Air Liner creates a beautiful and safe nursery environment and stays in place for easy and quick changes. Cribs are the best place for your baby to sleep, but little arms and legs can get trapped and injuries can occur. The Fresh Air Crib Liner is the parent-invented solution to fashionably improve the crib environment so your baby sleeps well and safe! This crib liner coordinates with the Just Born "Botanica" Collection (other items sold separately)
