Any musical moms here?

Unfortunately I cannot read music, but I try my best to always sing and do rhythm activities with my infant. How do I encourage my baby to learn music when I can't? I just looked up some music activity books (like the ones from John Feierabend), but they require the mom/teacher to be able to read sheet music in order to implement the activities. I really want my baby to be musical, but how? We attend Music Together classes once a week. What else? We have no "real" musical instruments at home like pianos, violins, saxophones, etc, so how will my baby even know what instruments are let alone want to play one.

All I know to go is put baby into lessons later. At what age should I sign baby up for lessons? What instrument?

Any knowledgeable musical moms with advice, please help.
