Ideas of playing w baby?

My baby is 6mths old, im a 1st time mom here, and i dont really have that much ideas of how to play w him. I do talk w him, i let him play w his toys, and interact w him about those toys. I also let him watch nursery rhymes, which hes really into. Sometimes i dont interact w him while hes watching. I also play mirror w him, i let him sit on his walker, bouncer. He has a lil bit of tummy time. I bounce him on the sofa, i lift him up in the air, sing to him.

Any other ideas? What do u do w your baby?
