Experts recommend waiting until your child is at least six months old before you jog with them (source). Before this time, your little one doesn’t have the muscle strength to support their head and neck properly. Running before they have that development can lead to whiplash and other injuries.
Always refer to your stroller’s instructions to ensure your child is in the right age and weight range. Never begin an exercise regimen without consulting your doctor and your child’s pediatrician.
