Taking the newborns out in public

Danielle • Cincinnati. 25. Wifey. Twin mom. 08.13.16💗💙
Our twins are a week and a half old today (born on the 13th) I'm just curious as to when everyone else started leaving the house with their newborns. I'm really unsure about it and kind of paranoid of germs (first time mom). I'd like to wait like a month before bringing them outside/anywhere. What are people's thoughts on this ?
