The Chariot infant sling is great for a tiny baby but once baby can sit up pretty well, it is not necessary. It says 10 months on the packaging which is true, a 10 month old baby would fit in it, but I don't think there are many 10 month babies that really need this product unless maybe the parent was dragging the chariot over roots or doing something really extreme
Pros
comfy and great for a baby with little head control
