The present invention relates to a partitioning component (210) for a feeding bottle device (100), the feeding bottle device (100) comprising a teat component (110) defining a teat volume (115) therein and a container component (120) defining a container volume (125) therein, the teat component (110) being attachable to the container component (120) by means of an attachment component (130). The partitioning component (210) comprises a first passage (212) allowing a passage of fluid from the container volume (125) to the teat volume (115) and a second passage (214) allowing a passage of fluid from the teat volume (115) to the container volume (125), wherein the second passage (214) is provided in the form of a one-way passage. The invention further relates to a corresponding feeding bottle device (100) and a feeding method. The solutions according to the invention reduce the risk of colic-like symptoms for the infant.
