I would be very careful with doing that! A dog that is great with children can be very aggressive when they have puppies. There instincts take over and all they care about is protecting there puppies. With first time moms I have been able to let my kids in to see the puppies ok on the first day but after that mom does not like it. I would let them come in and look if mom gets upset get them out of the room you have her in. I would not let the kids get down with the puppies and mom. If she gets upset she could hurt her puppies by laying on them or poking a hole in them trying to move them. If you want the kids to hold them take the puppy in a different room.
New moms are very protective of their pups and handling by the kids may stress her out too much. Mine are permitted to come in and look for a short period, but cannot touch until the pups are older.
Alot of times moms can get upset trying to get the pup back or protect it (instinct) and runs over the other pups, jumps around to check on the pup being held landing on the others....and even will go and frantically collect the remaining pups to huddle them under her and can injure them accidentally.
Alot deoends on the idividual female, the age of the child along with the childs relationaship to the dog. Just because she likes them in general, with new born pups it can be much different. Most of ours only allow me to handle the pups the first couple weeks.
Just be careful and if she seems upset or stressed back off.
Life isn't about waiting for the storm to pass. It is about learning to dance in the rain.
I allow my kids to "One finger touch" the puppies until their eyes and ears open. Once that happens, they can hold a puppy as long as either my husband or I are there. I know that my girl dog won't hurt the kids, but my kids are 10 and 6, so I don't take any chances.
Beautiful new babies. Mama and all are doing well.
