I'm home alone with baby and preschooler 6.5 days a week--getting really bored. I just thought since I take him in the baby jogger with his car seat for running and roller-blading--what's the difference if it's secured in the burley?

But I know there are people who are adament about not taking babies on bike rides until they are 1 years old. I was curious as to the specific reason. I don't want to harm baby. But as far as I can see, he would be safe in the car seat.
