I found my 2 yr old dd playing on her toy xylophone and using the handle to the toy vacuum as a microphone. She was singing loudly into her "microphone", in her little baby voice:
Baa Baa Blacksheep
Have you any wool?
Do you think she likes the wool on her bum? Maybe that's why her and her 3 yr old brother sing this song all day long? :LOL
