If this is her first litter she may be scared, it's a big deal We some times had this happen with a female we had we held her down and let the pups nurse. It sounds cruel but it's creuler to let pups starve usually after once or twice of holding them down(and petting and talking soft and gentle to them) its ok and they aren't scared any more. We did have one who would only nurse 2 pups (her choice of pups ) we had her spay to much work and the other pups just never seemed to reach there full potencals. If she isn't nursing this litter I personnal would have here spay. It's the fairest solution to all parties.
Also to help with the elemanation dampen the soft cloth with warm water it simulates the sliva and moistness of the moms tongue.
