The JPMBB Original and BASIC allow you to tie a knot before installing baby. Called "Basic Knot", it will then allow you to put on and take out baby without undoing it. So you'll never have fabric lying around on the floor and your hands free to focus on during setup. Perfect for beginners!
This basic knot is a special feature of Love Radius' self-tie wraps. This way, depending on the baby's age and needs, you can place baby in several positions.
