In actuality, crib bumper pads should never be used in the cribs of children under a year old, in addition, they can cause problems in children up to 2 years of age. They have been connected to cases of SIDS when children become trapped underneath the bumpers or against them, unable to pull themselves free. However, past the age of 1.5 years, this risk is greatly decreased.
However, this only applies to traditional bumpers. There is a new form of bumpers, the mesh breathable crib bumper pads, that are safe to use in cribs after a child is just a few months old. These bumpers allow children to breathe, even if they are pressed up against them. This means that even children who have rolled over onto their sides or faces will be able to breathe. These organic mesh crib bumper pads are usually made with materials such as bamboo and cotton. These materials are safe for use even with babies who have sensitive skin, making it easy for parents to relax. These materials are also easy to clean and are not prone to holding bacteria in, even if they do absorb spills and other liquids. A quick wash every once in a while will keep them smelling good and germ-free.
For children that are under the area of bumper use, you should make sure that they are carefully swaddled and that there are no blankets or padding that can get near their faces. This means that excess blankets, pillows should never be in the crib. if they are too young for mesh bumpers, they are too young for anything else in their crib. Simply dress them warmly, use a swaddling, or adjust the temperature in the room to make sure that they are kept as safe as possible.
