With the bjorn you can't nurse like a sling--though I'm hoping my sling will show up--but I could take my son walking in it while pushing daughter in the jogging stroller.
The tandem stroller I have is absolutely HORRIBLE for the road and sidewalk. What do you all think? Anyone like brisk walks and want to join me sometime? I exercise at they gym everyday, but my daughter loves the walks, and I just love my heart rate to accelerate so I can do a walk anytime but better with more involved.
