well, not a newborn, but definitely an infant. We used a Beco Butterfly II carrier when we started geocaching and our son was just 5 months. At a year, we switched to a backpack carrier by Ketly and now my husband carries him (he’s 21 months) around everywhere. He loves coming along and we make sure to dress him appropriately, pack some snacks and water, and check him for ticks afterwards, but so far, we’ve never had a problem! Have fun!
