is this bad?

So I have a 4 month old baby. my husband takes care of him in the morning usually so I can sleep and then he leaves for work and I take care of the baby for the rest of the day. my husband plays with the baby on a play mat we have and he gives him rattles and shows him little books and stuff like that. I do that at least once a day but when I take care of him I usually play with him by talking to him and I put him in his exersaucer and show him how to play and also I take him around the house with me while I do chores. I feel like what I’m doing isn’t good enough for his development as opposed to playing with the rattles and stuff like that. What do you think? I could be overthinking it but I wanna do what’s best for him
