When you need a little more height to reach for items up in a closet, kitchen cabinet or wherever, a folding step stool can provide a step-up, and then can easily be folded for simple storage. Just make sure that the step stool you do end up buying can carry the weight without buckling or collapsing altogether. And always be there when your little ones want to use it for reaching, just in case.
