thanks. i did notice that my girl, mimi wanted to nurse as long as i would allow her, lol! this was her 2nd litter and she seemed to grow tired of her pups from her 1st litter early on, but she was obsessed with her pups from this 2nd litter. she is now obsessed with my newborn pups from another mommy. she can't get to them, they are in a play yard but she has access to the room they are in and she wants them so bad. these little sweeties never cease to amaze me!
