I have the Fisher Price parking garage and a whole lot of cars and the boys and girls play with it every single day. I also have a kitchenette and a shopping cart full of dishes and those are out every day. Easel & chalk, washable markers and paper, finger puppets, dolls, blocks, we have a tunnel that I purchased at Ikea. Besides that there is a variety of musical instruments which I hide after a while, hehe, and by the way I got most of the big items used at yard sales, Value Village, Goodwill and bleached the heck out of them.

You don't have to spend a ton of money. My children love balloons and balls and bubbles and sidewalk chalk and letter boards and making a fort with blankets better than my expensive pop up tent that I bought for them. For the babies, I have a few walking toys they can push around and learn to walk. Just one more thing. For your own sanity, don't buy things with repetitive loud music or talking.

You can make your own playdo and buy paint at the dollar store and sometimes I even make my own fingerpaint with just a little flour, water and food colouring or shaving cream & glue and food colouring.
