As a mom, when I sort the clean clothes into stacks for the kids, I know 99% of the time what clothes belong to which kid.
As for Hubs...not so much. The worst part is, that was his reason for not wanting to help fold Mt. Washmore twice a week. He would say, "I don't know what belongs to whom".
So here was our solution.
We used sharpie and marked #1's clothes with a 1.
Respectively marked #2's with 11,
#3's with 111
and #4's with 1111.
This way, when #1 out grows a shirt/shorts/pants, all that must be changed is adding another 1.
It makes it sooo much easier to sort the laundry!
