I do not touch the babies. The babies are ten hours old already and still cannot get some milk. Is it fatal to the babies

The mother cat could be seriously ill. The kittens could die quickly.

Here is advice from a cat/kitten site: FAQ - Mother cat will not feed newborn kittens (http://cats.about.com/od/faqspregnancyandbirth/f/newborn.htm)

Call your Vet, get advice, go from there.

And, yes, not eating is fatal.
