Does the Parent's Hoodie have to be used with a baby carrier / a baby wrap or does it stand on its own?

No, the Parent's Hoodie is not sufficient for babywearing on its own. The Parent's Hoodie is not a baby carrier, its mission is to cover you from the cold when you carry your baby. You can use it with the baby carrier or the baby wrap of your choice! But ours work so well together, don't they?😉
