What toys do your little ones love?

My son is about 12 weeks and I realized this week he gets bored and is ready for toys. I had a crinkly book with a mirror in it and he literally cracked up SO hard at it it was like the best moment I've had with him so far! So now I want to get him more toys but I don't know what he should be playing with at this age. He's been wanting to put everything in his mouth so are teething toys good? I really have no clue about baby toys whatsoever. I feel dumb. Lol.
