They are so big. The girls love the new car seats as they were too heavy for the baby ones. The only thing I really do not like about our big old van is that it doesn't have the ability to secure the newer seats into the same row. Only the middle seats have the extra bar to secure the seats too. The twins prefer to sit side by side. Oh well for now this is what we have. They are getting bigger by the day. At 13 months old they are on the verge of walking and are now safe and secure in front facing car seats.
