Musical chairs at dinnertime?:-)

Sounds as though you have a great event planned; good for you!

Singing at bathtime can be fun. I second Sorcha's suggestions. Also, to get relatives involved, how about children and their parents asking grandparents, aunt and uncles, friends, etc. to exchange songs...of their eras, or their favourites?

Teaching songs: counting, abc's, etc. where everyone can clap out the rhythm, etc.

Dancing - teaching dances to certain types of music; dancing with the pets, etc.:-)

Making up songs, together, i.e. a song about "mom," themselves, the pet dog, etc.

A visit to Mudcat!

Have fun,
