It is best not to let her near the pups after she has eaten.
I fidn it easiest to fed her after the pusp have been fed,and she has topped them up at the milk bar, this means she can finish off what they have left as well as eat her own and they are of course full up so less stimulus for her to provide sated pups with food.
She won't need to go back to them for at least an hour or two.
