I have a one month old. We are taking her to a Christmas Light display this weekend and it is going to be cold. I have a Graco travel stroller. Does she need to be in the car seat to be in the stroller, or can I have her in the stroller by itself with it laying down. I think she would be warmer if I bundle her up in a bunting that we have (and I really do not want to adjust the straps in the car seat). She will be able to see more if I don't have the car seat cover over. Thanks in advance for your help. As you probably already guess I am a first time mom. (sorry about the italics, i don't know what I did)
