A baby bottle device (100) is provided which comprises a fluid container (110) for milk, tea or water. The baby bottle device (100) furthermore comprises at least one movement sensor (140, 150) for detecting a movement of the baby bottle device (100). The movement data from the movement sensor (140, 150) is analyzed in an analyzer (200) to perform a suck-swallow-breathe analysis during a drinking phase of the baby based on the movement data from the movement sensor (140, 150). Thus, a drinking behavior of a baby can be efficiently analyzed.
