Just wondering if anyone had any comments on how well the MR fits small babies. Like 5-6 lbs and short? We found out today that baby girl is going to be very tiny (she is measuring 3 weeks behind right now.) and that she will most likely be tiny at birth. I am hoping she is at least 5lbs so she can use this seat to bring her home, but I know that if she is smaller and able to come home we will have to get something else.
