Q. Our Rabonim where wondering, if one has to feed his small children before he feeds himself and this happens to be a Biblical mitzva, how come that whenever we make Kiddush or on every Seuda or meal the children are served last?
Are we not transgressing constantly on a Biblical mitzva and prohibition?
A. Horav Shlomo Miller Shlit'a explained that the time lapse at a Kiddush or Seuda between serving the kids first to eat or the grownups is so small and inconsequential, that other priorities such as honoring parents, Rabbis, or guest take priority.
