Henry has outgrown his previous baby carrier. We don’t use it that often, but have actually used it more lately, because of all the snow we aren’t able to use our stroller. Eventually we will definitely want a back carrier for when we go on hikes etc. I’m wondering if we should just buy the Ergo 360 carrier (can be worn 4 different ways- baby front facing in/out, side and back positions). It says you can use it until they are 45 pounds. Does anyone have this carrier and experience with the back position of it? Is it worth it or do you think I should just get a backpack style carrier instead?
