Bed rails for children keep young toddlers from falling out of bed. The ability to keep oneself in the bed, moving back to the center of the bed when too near the edge, is a learned behavior. Children moving from a crib to a bed will frequently roll off the edge. Even if it does not hurt them, the fall certainly startles and upsets them.
Generally, when a toddler starts to climb out of the crib, or if they are able to climb up and down out of a regular bed on their own, they are considered ready to move from the crib to the 'big' bed. Some children may note feel safe at first, after the comforting confinement of a crib. Bed rails for children new to the big bed can offer them protection from falling out, as well as a sense of security.
The types of baby bumpers used for toddlers should not be confused with the bed guard rails used by adults. The adult version usually has large openings through which a young child can crawl or become stuck. The types designed for children usually have padded frames with mesh stretched over them to prevent the child from becoming entrapped.
Most of the devices come with a clamp that attaches them to the mattress...that way they are easily removed once the child becomes better at staying centered in the bed. The better-designed bed rails for children also fold down out of the way, since young toddlers are frequently still in diapers, and changing them in bed is easy, unless you have to reach over the rail.
