Number of sides
When you’re shopping for crib rail covers, you need to decide how many sides need attention. If the crib rests against a wall on one or more sides, your baby will probably have a hard time chewing on those sides. Sides with elevated, sleigh-style rails also may be poor candidates for gnawing. If your child has already started chewing, cover his favorite rails and any others that are the same height and shape. If you’re creating a baby registry, it can’t hurt to add enough to cover all accessible rails.
Size
You’ll also need to think about your crib rail’s measurements. While crib rails are generally the same length, their thickness can vary greatly. If the cover is too small for a thicker rail, the fasteners may not meet and attach securely. Older babies may be able to easily unfasten crib rail covers that are ill-fitting on slender rails. Additionally, crib rail covers that are too small may not adequately protect the wood against aggressive teethers.
