So, the current carseat I have is the EvenFlo- Journey 200 Travel System. The car seat has a weight limit of 35 pounds and a height limit of 30 inches. My son currently weighs 16 pounds and is approxiamtely 26 inches. Well, he will out grow it in length WAY before he outgrows it with weight. He's 10 months old and we are having problems with his weight gain, that is a whole other story which I am NOT getting into right now, so he is small for his age.
My question is: should I switch when he outgrows it in length or wait until he reaches the 35 pound weight limit? I know babies should get kept rear facing until a year and i think there is a certain weight limit as well. What convertible car seat would be best for when we do switch?
