when does a baby car seat position change ?
you should change the car seat once the baby hits the weight limit or does not fit comfortably anymore. I had to switch to a rear facing convertible seat early with my second because he was a big boy, those go up to 30-40 lbs and can be rear facing until he hits 1yr and you can then turn it around. Infant car seats usually only go to 20 lbs, so it is probably time to get a convertible seat. posted 01/19/2011 by Leslie61.
