Years have passed since the chaos of the Baker family’s twelve-child household. Now an adult, Charlie Baker is starting a family of his own. Believing that growing up in a large family has taught him everything he needs to know, Charlie feels confident about becoming a parent. He and his wife are expecting their first child and are excited to begin this new chapter.
However, once the baby arrives, Charlie quickly realizes that parenthood isn’t as easy as he thought. Sleepless nights, constant crying, and work-life balance issues start to wear him down. Just when things couldn’t get more overwhelming, his siblings begin showing up — each bringing their own kids and their own set of problems, turning Charlie’s quiet home into a familiar mess.
A surprise family reunion brings the entire Baker clan back together under one roof. As old memories resurface and sibling rivalries reignite, Charlie learns that no one ever really has parenting figured out. Amid the chaos, laughter, and heartfelt moments, he begins to appreciate the beauty and madness of the big, loud family he once took for granted.
Cheaper by the Dozen 3 delivers a warm and funny look at modern family life, blending new beginnings with nostalgic moments. Through all the ups and downs, the film reminds us that family — no matter how chaotic — is the one thing that always brings us back home.
