KAZOOS!! 3 yo’s often have a little trouble getting the hang of “humming” rather than blowing into a kazoo, but once they get it, they can use their “mouth wind” to make some great music.
I can’t take credit for this because I saw it in a book but the song is sung to the tune of Bingo. It goes like this: Their was a day when we were blown and windy was the weather, W-I-N-D-Y,W-I-N-D-Y,W-I-N-D-Y, and windy was the weather. Continue substituting a clap for each of the letters in the next verse.
