Baby wearing

Expecting 2nd kiddo in November … my oldest is a very active 3 year old, how many of you found a baby carrier/wrap very efficient and a must have item for your second time around? TIA. 🙂

P.S. We go out often, preschool drop off and pick up, shopping, visit family and adventuring. I use a backpack for a diaper bag and just don’t know how great a back pack and carrier would feel vs. a stroller to just toss everything in lol.
