The game progresses through many different mini-games such as taking pictures of the baby, feeding, washing, burping, rocking it to sleep, changing diapers, playing with a seesaw or a mobile, stopping it from crying etc. Each mini-game has a different lay-out and controls, often based on timing correctly with room for a few mistakes. Based on the final result a bronze, silver or gold medal is awarded. If the movement of the plush doll is too violent, the game pauses briefly and displays a warning. There are multiple environments such as inside the house or outside in the park. There are six babies to choose from, unlocked gradually: Daniel, Emma, Koyuki, Lucy, William and Yuto, each with their own baby book with six pages to unlock.
Other types of mini-games include feeding multiple babies at once, a crawling race, pushing a swing, a simplified tug-of-war or collecting bottles. The mini-games can be practiced in a training mode and by completing them in the story mode various unlockables are opened up. The game is split up into several levels (pages) with four to five mini-games each. Some of the mini-games are based around mama when she has to swat flies or climb a tree to retrieve her hat. The game has a versus mode for two players simultaneously, each controlling their own doll. After completing the game it is possible to view an album with pictures of all of the baby's activities.
