You really should not separate the pups from Mum, (unless you must really leave the room to go to the loo, and then it is better to let her out of the room for toilet herself while you go) as you need her to bond with them, and for the first three days they should basically be feeding almost constantly, to bring the milk supply in.
She needs to learn that they are her responsibility, your job is to watch her and plug pups on, rescue them if she is clumsy. You should encourage her onto her side and preferably get her to lay on the other side when you have taken her out on lead to toilet. Let her run back into pups.
Many bitches can be conflicted between their maternal instincts and their attachment to you and her normal routine, so make it easy for her. Feed her in the whelping box, stay by her so she c an concentrate on pups.
Weigh pups twice a day for first week, to ensure they are gaining.
It is normal if pups are big to have4 a loss the first day, regain the next and from then on put weight on.
Lack of sleep for us is par for the course if you want all or most of the pups to survive and thrive.
