我是大姐姐，我的妹妹要用奶瓶喝牛奶，而我長大了我可以用杯子喝水;  我是大姐姐，我的妹妹吃蛋糕用手挖，而我長大了我可以用叉子吃蛋糕。藉由身份的轉變，以翻頁的方式，讓大哥哥大姐姐發現了自己的成長，與弟弟妹妹的不同，是與大寶貝的互動好書哦~

Babies sure have a lot of growing up to do! They can’t eat with a fork, sleep in a real bed, poop on a potty, ride a trike, or read a book. On every sweet lift-the-flap spread, Karen Katz’s illustrations celebrate the varied accomplishments of older siblings who may be in need of a little ego-stroking after a new baby’s arrival! Each book ends on a warm, loving note with the older child reassuring the baby that "one day you’ll be big like me."
