Smudge is always singing. Yes, singing. She hums and sings, and sings and hums all throughout the day. Sometimes I can catch a hint of a tune, but other times she seems to be making up her own songs. Brother Jboy is getting into the act too. He likes to bang out a tune on the piano but he hasn't started humming or singing yet.
After a few more sessions with his sister I think he will be humming right along with her.
What a pair.
