I work with families and one of the biggest issues I hear is that during the week everyone is super busy and pressed for time. If they are going to clean or organize, the best time is on the weekends. I like to make things simple and easy yet practical and still organized on some level. Here is one way to achieve all of that:
Use large baskets, decorative storage cubes or other containers for “catch-alls” and quick clean-ups. Have a basket/cube/container in the kitchen for quick toy, crafts and book pick-up. Have a container (labeled with their name) for each member of the house in your entryway. They can dump their things there. I suggest entryway (mudrooms work too) because you want to keep the potential mess from the rest of the house. ANd any family can see something that belongs to another family that is NOT in its right place and put in that persons container. This also eliminates the never-ending question, “Do you know where my _______ is?” If someone left it lying around, they’ll most likely find it in their container. Then designate a day that everyone must clean out their box. I might schedule it every Friday night or Saturday morning.
