-----Answer-----
carefresh and soft-sorbent are great beddings for pregnant hamsters it's soft enough to burrow and carefresh can be easily chewed up and made into a fluffy bedding.

Answer
Are you leaving the male in cage with her after giving birth? Do you leave her alone and give her privacy with the new pups? There could be many reasons why the babies aren't living. She could be really stressed over the fact that the male is there, she could feel threatened or she could feel that something is wrong with the babies. More than likely she is pregnant again as it is very easy for hamsters to get pregnant.
