We have the stroller since it was given to me by a friend, but it doesn't have the attachment for the car seat so I had to go out and buy it. Baby should be able to sit and hold up their head on their own so they aren't flopping all over the place...especially with uneven ground. I'm "attempting" my first run tomorrow with the stroller...let's hope I survive!
Re: BOB SE revolution
we have the bob revolution and are still using the car seat adapter. he is two months today and about 11.5 pounds.
we take him for walks on some gravel trails and sidewalks, no official trails yet.
i didn't think you were suppose to run with baby until 6 months? original poster i know this was not your concern!
