Great baby toys 6m+

With Christmas coming up I find myself stuck in what to buy my son for his first Christmas. I mean after all, what do you get a baby for Christmas?

What are you baby’s favorite toys? Your favorite toys for them?

I realize, I could just buy him essentials but he’s intrigued in toys and I’d love for him to have them. Especially if they’re educationally/good for his development.

TIA!
