I have toys out that they can play with all the time if they choose, cars, work bench, kitchen with some kitchen food/pans but most is put up on shelves that I switch up.
For myself, I've found that when I had everything at the kids' level, they just brought everything out and then had a big mess and not want to play with anything getting a little overwhelmed.

During the summer months- most of our days are outside and the toys outside are left in the sandbox and clubhouse
