#GS4 has a toy xylophone that he loves to play with. At about six months old, he hasn't yet mastered hitting it with the attached mallet thing, but he makes the motions and occasionally strikes it, making a tone. I told my daughter-in-law that I foresee the day when he asks Grandpa for drums.

She says he likes it and plays with it far more than #GS3 ever did.
