The narrator tells us that the baby is a naughty boy who cries when he's awake. He's got a nickname: "big head" . The narrator asks if they've given him a name yet, and the narrator says they haven't yet given him one. The baby's name is "rourou" , which means "little brother." The narrator says that she can't take the baby as her little brother, because he is too small to talk. She says that he'll grow up to be a big brother, and she'll call him "my little brother" when he gets older. She tells him to feed the baby in the bedroom, because the baby needs to be fed. She'll wait for him in the hallway, and he should let go of her.
