I would absolutly mention it to mom. But I would do it in a funny kind of "oh, look what dad did, how do they function without us" way. Maybe mention on a case by case basis.

" I think daddy pulled the wrong clothes out of the drawer for little timmy today, he kept tripping on the hems"

And I would continue to mention things to her. After a while she'll get the hint. When I used to travel for work I would leave out 5 days worth of clothes for my husband. That way there were no questions, he just put on what was ready for them.
