... & how old were your kids?

Mine are in Kindergarten and 3.5 in FT preschool. I WOH so they don't have too much to kill inside the house. The kitchen is in our kitchen/dining area. After Christmas I realized I haven't seen them play with it for a month or so. Longer for my older one. They both prefer to help in the real kitchen. I'm tired of straightening it up and the junk we end of stacking on top. Is it time for it to go or is this just a lull in use?

Any tips on getting rid of big things that the kids will obviously notice?
