Especially if they are plastic. Children are often more enthused with the parts that come off than the toy itself. Teach older children the importance of this. Make it a private place for them to play. Encourage older children to play only in their room when playing with small toys or games with small pieces.
Balloons are a popular toy for small children.
Supervise your child if they are playing with a balloon. Balloons will often pop or deflate when they are playing with them. Pop the balloon and secretly discard the pieces once it starts to lose air. A child may want to imitate you and put a cigarette butt in his mouth. Store these items safely.
