Josh and I went last week Thursday to buy Lillian and Claire's convertible car seats. We bought the seats that will transition with them all the way into a booster so this is the last car seat we will have to buy and I love that! Saturday they went on their first ride in them and they seemed so happy. They are able to sit up so much more upright and check everything out. Actually, I think I would love to ride in one of their chairs, they feel so comfy!
