Well, no ... Rand was very clear about it. She meant exactly what she said: every man is an end in himself.
Your attempt to modify her statement is actually quite instructive: if you ever start trying to dissect Rand's statements, you always seem to end up adding those little "implied" modifications that are necessary to get around the logical difficulties of her claims.
Remember: Rand basically claimed that her "Objectivist" principles were essentially "natural laws." The need to infer such "implied" modifications to her claims is a very serious problem.
It eventually ends up in one of two places: either you decide to accept Rand's basic premises on faith; or you give up on Rand altogether. I chose the latter route.
When I read the book it seemed as though she was repeatedly describing my thoughts for as long as I can remember - at least since I was two! The sex stuff was a bit much, but otherwise she speaks for me, very precisely. Accordingly, I am comfortable saying that she would laud anybody who loves living for their children, as I do (and would not confuse it with altruism, which is evil). The fact that she was childless is imaterial.
