Children rarely appreciate what their mothers do for them (until, perhaps, they have children of their own), so it is a real chesed shel emes (true kindness) to care for small children.  If a housewife had the opportunity to perform these same tasks for, let’s say, the Chofetz Chayim, she would certainly be happy to do them.  It is no less a chesed for one’s own children. ~ R’ Chayim Pinchas Scheinberg zt”l
