When my newest is born my little will be 2 years old. we have planned to use her 2nd convertable car seat for the newest. I never used an infant seat last time around, so thought.... Why this time? Save some money, but my little is.still carried usually from car to in stores 70% because this is what she wants, other because shes a wild child, doesnt listen well, so its the safest. She won't go in a carrier anymore. Which do you think would work best for convenience an infant seat or just a baby carrier for the newborn?
