Exposing new born baby/mom to outdoors

Liz

I’m Mexican and there’s a lot of things we do different as far as taking care of mommy/baby after birth compared to other cultures/races. For example we’re told to stay covered and not expose ourself to air, cold, any outdoors, stay away from certain foods, bed rest for 40 days, etc. One of the big ones is not letting our babies be exposed to the outdoors for the first 40 days of life. Have any moms & baby not followed any of these suggestions and had no issues?
