Dreaming about feedings usually occur in the first few months of life when babies are not yet able to feed themselves and still rely on their parents for sustenance. When you dream of feeding someone else it could signify your feelings of giving in to others feelings and needs at the expense of your own.
It could also represent comfort, love, care and nurturing because you are satisfying another person’s needs for food like a mother does for her child.
Feeding someone else in a dream might also suggest that you feel powerless to take care of yourself because you have too much on your plate, so instead you have been taking care of people around you instead.
