Bell Bracelet
Cut a piece of elastic cord long enough to go around your child's wrist or ankle plus a few extra inches to tie. String several jingle bells onto the cord and tie shut. If you don't want the bells to be able to move around, make a knot before and after each bell is strung on. (Tying like this ensures that if the bracelet falls off, the bells won't come off the cord.)
When your child wears the bracelet they can make music by just shaking their arm, or turn on some music and dance, dance, dance!
