Even though some jogging strollers can be used from day one with an infant car seat, it is not recommended to run with a baby until at least 6 months (some even recommend 8 months or older). “Ultimately, you will want to defer to your pediatrician. The manufacturers of jogging strollers often recommend waiting until the child is 6-8 months old,” says Norris, adding that it may be different if your baby was born prematurely. “Your child should be able to hold up their own head and chest. While some jogging strollers have car seat attachments, these are for everyday use and may be too unstable for runs.”
