Hello ladies! My husband and I are in the process of transforming our den into our daughter's playroom. No one ever sits in our den, we're always in the living room when we are home. So we're going to just donate the furniture in there and turn it into a playroom. It sits right across from my office so I can keep an eye on her while I'm working during the day. I need some recommendations on the types of toys or any objects to put in there. We already have a foam mat, gate (I believe it's called Superyard, it's a colorful gate), vTech sit to stand learning walker, jumperoo, and a few educational toys (magnetic letters, ABC blocks, Teach My Baby Learning Kit, Manhattan Toy Activity Cube, Fisher Price Laugh and Learn Smart Chair.) She's only eight months (about to be nine months in a few days) so I know it's not a lot to put in there right now, but please give me any recommendations. Any recommendations on toys or other items?

*I know someone is probably going to recommend books, but all of her books are in her nursery on the book shelf.*
