A typical doorstop has two pieces, a metal spring and a rubber end cap. This type of hardware can be a hazard for young children in the home.
An alternative for a two-piece doorstop is a one-piece plastic doorstop, which has no sharp edges, springs or removable end caps. This doorstop is a "child friendly" substitute for your home. It provides the same conveniences of a traditional doorstop with shock absorbsion and wall protection, but doesn't have the safety hazards.
A one-piece doorstop will aid you is achieving a "child-proof" home.
