Newborn German Shepherd puppies

Jacqueline

My German Shepherd had 10 puppies 9 days ago and doesn’t have as many nipples as she does puppies. I try to make sure they all get fed but they want to eat all day and the mom keeps trying to leave the the room and not even to only go outside I’m not sure if she’s rejecting her puppies or if she’s just tired from getting sucked on all day does anyone have any tips or anything? Thank you!
