I've been really excited about that idea of getting a Bob jogging stroller to use once baby is here. But, just recently, I've been reading that you aren't supposed to jog with baby until baby is at least eight months old. Is that accurate? The Bob comes with an adapter that allows you to put your car seat inside the stroller for infants for added safety and stability. But, according to the Bob website, this adapter is for walking, not running. Do I really have to wait so long before I can jog with baby? Anybody have any wisdom or experience they can share?
