When did you leave the house with your newborn?

My baby will by 1 month tomorrow and I haven’t gone anywhere besides the doctors. I really would love to go shop around or get out ( mostly for my mental health ) going outside isn’t really the best option as it’s really cold here right now. When did you take your newborn out? I don’t have a carrier car seat so I would either push him with the bassinet stroller attachment or baby wear him, not sure which is safest? Obviously I would try and avoid people , go out on a weekday morning and not let anyone near him. I would love to hear advice and what other moms did!
