The invention comprises improvements in crib
extensions.
Cribs presently employed have either fixed sides
or are of the type wherein one side is fixed and
the other side adjustable to either maximum up
ward or downward position. An agile infant can
grip a top rail and pull itself up and over the
crib side or sta-nd on available objects, such as
dolls or toys and climb out, often resulting in
serious falls and injury.
Generally, the invention comprises a pair of
