Activities / play with baby

My baby is 13 weeks. We have a pretty set routine, we go out for walks, read books, sing nursery rhymes, do tummy time, play on activity mat (on that he does mirror play, kicks and pulls at the hanging toys) we have a sensory basket where he will lay on foil and kick around and feel the different materials and he also has another acitivity gym with a piano on it that he can kick. Just wondering if this sounds similar to your day or is there anything that you do that I haven't mentioned?
