As your baby grows, you can easily adjust the height, leg position and seat area. The pressure-relieving waist belt sits at the waist when you carry your newborn, and as your baby grows, you move the belt down to your hips. Good head support is essential to help your baby hold their head in an upright position until they have the strength to do so unaided. Baby Carrier Harmony has easy snap adjustments for the head support in three positions. Use the position that provides good head and neck support and gives you good supervision of your baby.
