For the older child who's about to get a new baby brother or sister, and the mix of excited and unsure that comes with it. Pick the one that fits your child. Every book here names the honest feelings, the jealousy, the where-do-I-fit worry, and lands them somewhere warm: proud to be the big one.
Pick one, or a couple. The two board books, I Am a Big Brother and I Am a Big Sister, are the shortest and most reassuring, made for the youngest child; hand over the one that matches. There's Going to Be a Baby is the honest, talky one that lets a child admit they're not sure. Peter's Chair is the classic that names the jealousy without ever saying the word. Big Sister and Little Sister speaks to the pride and weight of being the big one, and 101 Things to Do with a Baby turns 'the baby takes all the attention' into a whole day of jobs only a big sibling can do. Different doors into the same warm room.
