10 Best Books About Becoming a Big Sibling

Preparing to welcome a new baby into the family is such a special journey…and if this isn’t your first go-round, that journey now extends to your soon-to-be oldest child! Toddlers and young children likely have lots of questions about the new baby on the way, but they might not always be able to express their concerns (or insecurities)—and that’s okay! 

One great way to help your “big” kid process any doubts, fears, and yes, excitement, over a new sibling's arrival is through books. Some books answer their big questions in age-appropriate ways. Others focus on the special bond siblings share. Still more are designed to remind Big Bro or Big Sis just how important and loved they are. No matter what big sibling book you’re looking for, your new favorite is sure to be on our list!
