Yes, the Doona is designed to be used only for infants. It is a car seat and stroller combo that is specifically designed for babies from birth up to 35 pounds or 32 inches in height, whichever comes first. The Doona is not suitable for older babies, toddlers, or young children, as it does not provide the necessary support and safety features for their size and weight. It is important to always follow the manufacturer's guidelines and weight limits for any car seat or stroller to ensure your child's safety.
The Doona+ is primarily an infant car seat, and like any infant car seat, is not recommended to leave baby in it for longer than 90 minutes at a time to help with breathing.
