A kit of parts for a feeder [1] has a body [2] and a bung [8] which can slide within the body [2]. A periphery of the bung [8] can form a sliding seal between that periphery and the internal side walls of the tubular body [2]. A base cap [11] has an aperture [12] through it and is mountable at a lower end [4] of the body [2] to substantially occlude that end [4] and to allow airflow through the aperture [12] into the body [2] as the bung [8] moves away from the lower end [4] of the body [2]. The kit of parts has a teat mouthpiece [9] for liquid foods, a sipper mouthpiece [41] for pureed food and a spout mouthpiece [51] for mashed food and a pump attachment [61]. The pump attachment [61] has a pump and a spoon [63]. The pump has a pump bung [72] which moves reciprocatingly within the body [2] and which forms a sliding seal with the internal side walls of the body [2]. A valve [77] allows food to flow from the feeder [1] but prevents the flow of food into the feeder [1]. A feeder [1] is also disclosed.
