My 4-year-old grandson used to say “play wiggles” and I’d have to say that’s just in Gummy’s car.
We generally turn off the music and have lively conversations instead… but he gets SO MUCH music at home. His dad and mom are musicians and practice all the time singing the praise music they play at church. He knows all the words and sings along too loud. And of course he adds his own special choreography.
