The bouncer has two sides:
The baby side can be used from the time your baby is newborn until they can sit up unaided. The baby side is designed for young babies and has a safety harness that should always be fastened. The safety harness has two different fastenings to allow you to adjust the size to fit your child.
When your child can walk and sit unaided, turn the fabric around and use the chair side. Your child can then use Bouncer Bliss as a chair. Your child will no longer need to use the safety harness, which is not possible anyway when the chair side is used.
