Playing with baby

My baby is a month old now. When baby is awake during the day I read, sing, or do tummy time on my stomach. I don’t ever do this stuff for too long. I honestly feel kind of silly doing it, but the great ol’ internet makes it seem like my friends are doing a lot of playtime with their babies and I wonder if I’m not doing enough. We don’t have one of those “play gyms” that are $50-$100, and our guy usually spits up when he lays down like that anyway 😂 Do you play with your baby?
