Mama wa Shougaku 4-nensei

Young Natsumi Mizuki is an ordinary fourth-grader whose biggest concerns are her friends, school, and maybe a little crush. Her world is turned upside down, however, when a mysterious package arrives on her doorstep, containing not a new toy or a fun game, but a baby! This isn't just any infant, though; this is the future Mirai, Natsumi's own daughter, sent back in time from 15 years hence. Suddenly, Natsumi's simple life becomes a whirlwind of secret feedings, hidden diaper changes, and ingenious schemes to keep Mirai's existence a secret from her parents and classmates. Balancing elementary school with the monumental task of raising a baby creates a constant comedic struggle, but also forces Natsumi to confront what it truly means to be a family, and to understand the profound love a mother holds for her child.
