Yes you have to separate the male gerbil from the female with her babies because if you leave the male with the female and her babies the male will kill them.
Sorry but you can't. A male and a female gerbil will have dozens of babies every month or so. Sorry again,Daniel Merry

A)Elderly gerbils moms will kill their babies if she has been bred for an extended period of time. B)Another answer: If the human scent gets on the baby gerbils before they grow hair, then the mothers will kill them because of the different scent.
