The invention relates to a feeding bottle device, feeding method and a partitioning component (210) for a 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 air and liquid between the container volume (125) and the teat volume (115) and a second passage (214) allowing a passage of liquid and preventing a passage of air between the teat volume (115) and the container volume (125). The solutions increase the user convenience when operating the feeding bottle device without increasing the risk of colic-like symptoms for the infant while feeding in a horizontal or near-horizontal feeding position.
