Lucile Packard's Children's Hospital 3-4 on Saturdays (any time slot between then): there's no piano, but you can bring any instrument you'd like.
Lytton Gardens 2PM on Saturdays and 3:30 on Sundays: bedside volunteering, as well as general volunteering, and there is a piano.
Opportunity Center 3-4 on Fridays: No piano, but interactive workshops (teaching kids songs) are more welcome. Performances are also great.
