3 month old appropriate toys?

Taylor • 22. 2 Cats & Ollie 💜
My baby is almost 3 months old but doesn't really play with anything he held his paci for like 10 secs the other day..or he just pulls my hair. when am I suppose to start buying him toys? What kind of toys does he need? I have a tummy time mat and a swing but that's it.. I'm not sure where to start? Or at what age they need things for entertainment?
