Babies can typically start using a jumper when they have developed good head and neck control, which usually occurs between 4 to 6 months of age. It is important that the baby can hold their head up steadily and has enough muscle strength to support themselves before using a jumper. Babies should also be able to sit up independently to use a jumper safely and effectively. The use of a jumper is generally recommended for babies who are not yet walking and weigh under the device's weight limit, usually around 25 to 30 pounds. Usage time should be limited to 10 to 15 minutes at a time, no more than twice a day. Parents should always supervise their baby in a jumper and consider their individual developmental milestones and readiness before starting use.
