We have an instep grand safari swivel wheel jogging stroller. It says in the instructions not to use it with babies less than 4 months w/o popping an infant carseat in it. We do have an infant carseat which is compatible with it, but I'm wondering why we can't just put a new baby in it in the regular seat with the seat all the way reclined? The seat reclines almost totally flat (maybe 175 degrees), and we would NOT be using it for jogging or on dirt roads with a newborn. We would only be using it for regular walking down a nice, flat, even sidewalk...no bumps, no dirt, no running, just regular walking. It seems to be me that it really wouldn't be any different from a regular stroller since it reclines almost totally flat.
We do a lot of walking and live someplace where it it is hot/humid almost all year. I do babywear, but also use a the stroller a lot since babywearing in the heat/humidity isn't so much fun. Baby is due in Sept, so it will definitely be very hot/humid and we also have a 4-yo that is in and out of the stroller a lot on walks. Being able to share the stroller between the baby/ the 4-yo on walks (ie. babywearing when the 4-yo is tired and wants to ride) seems easiest, but it would only work if we could use the stroller with the baby w/o the infant carseat. So, am I missing some reason why this isn't safe??? I can see how jogging or dirt/unpaved roads could be dangerous, but I'm not seeing any problems with just regular walking with the seat being almost totally flat.
