Newborn. Routine or not?

Roxanne
My baby is almost 8 weeks. Is it too early to try to enforce a routine? Right now she's basically feeding and sleeping on demand. Some days she naps well some days she doesn't. When I google routine for newborn, I was amazed how some moms have their babies on strict schedule but I can't seem to get the hang of it yet. Am I doing something wrong? Or is it ok to let her sleep and eat whenever she wants? 
What do you moms do?
