End decision fatigue
There are few things that are more of a time-suck in our household than getting dressed every day. Why? If you’re like me, it’s probably because your kids have too much stuff.
Kids only need five outfits each week. Store the rest in bins in the closet where they can't reach them and rotate out other articles of clothing if you must. Then, stock their closets and drawers with only items that are interchangeable and season-appropriate. Fewer options mean less battling for you and less decision fatigue for them (it's a thing, and kids get it, too.)
Another awesome trick I use along these lines: I have only one style and size of socks for all my kids. That means if you find two socks from different locations in the house they automatically match! Plus, I leave a basket of socks right by the entryway where shoes go to make it that much easier to find them.
