Sure! but there's one caveat: you don't really want a lot of people touching or holding your baby--that's how infections spread.
Being outside on a nice day, going for a walk in the neighborhood, maybe strolling through the mall, all of that would be fine, and it's a good idea to get out at least once in a while. But when people want to get in your baby's face or hold her or touch her, say "no.".
