Suitable from birth. Designed for maximum comfort for baby and parent - you wear the harness like a jacket and can adjust the straps one-handed for a perfect fit. The soft breathable baby pod is fully adjustable and has a unique hand sleeve for easy fitting. Plus there's lots of support and ventilation to keep baby cool. Best of all you can remove the pod without disturbing baby. Buy two harnesses would mean that Mum and Dad could share the load.
