How old do you think my baby rats are?

When I posted about them yesterday you guys said that they were too young to be away from their mom, the person I got them from said that they were just weaned and they were 8 weeks old, when you guys said she lied to me I brought it up to her and she blocked me, should I look into getting them some milk or do you think they will be fine? They're eating solid food just fine and they don't have any issues with drinking water
