I don't think I waited at all. Maybe with my oldest but I don't remember

OK I just had her Saturday I'm dying to go shopping but I don't want her to get sick

for a walk I think 2 or 3 weeks, but I was going out with my son 4 time in first week for blood tests and doctor appointments, and it was really bad winter, but he never been sick or anything, so I think if you dress and cover baby properly to the whether, baby will be fine :)

first appointment a couple days after delievering.
