Agree with Brainless. I don't make my bitches go in morning, noon or night!
If she wants to sleep with them, it's up to her. And if she wants to feed them, it's her choice. I don't ever make the choice for them. I just ensure that mum can get away from pups if she wants, and pups can't follow.
Most of my bitches give pups a comfort suckle on the day they leave home.
