A majority of experts agree that a jogging stroller should not be used on a child younger than six months. The main reason is that most manufacturers don’t offer fully reclining seats which makes them only safe for babies between the ages of six to eight months and above. The medical reason given for parents not to use joggers on younger babies is because such babies have not yet acquired the necessary neck and head control when they are in a sitting position. They, therefore, can't withstand sharp turns made when you are jogging or the fast movements that come with you pushing the stroller when jogging. Parents are further advised always to follow the manufacturer’s guidelines and also check for any possible recalls.
