The pups were a little pre-mature, so their suck/swallow instinct was weak. (Spoke to the vet early this morning, his suggestion was just keep "messing with them, til they get it!")
I "milked" the Mom, into a syringe, and fed the pups, all day, and as I was taking the syringe out of their mouths, I slipped them onto a nipple, and milked it. They only held on for a short time, each time, but they are staying weakly on now, they bump off easily, but go back to it!
YIPPEE!!
p.s. thanks for the bumps!
