The invention relates to a feeding device (1, 1', 1'') having a hollow form, the feeding device (1, 1', 1'') comprising: an inlet portion (2, 2', 2'') having an inlet (4, 4') for entering nutrition(13), and a suction portion (3, 3', 3'') for sucking the nutrition (13) through the inlet (4, 4') into the feeding device (1, 1', 1''), wherein the suction portion (3, 3', 3'') comprises at least one opening (5, 5', 5'') for dispensing the sucked nutrition (13), wherein the inner surface (6, 6', 6'') of the feeding device (1, 1', 1'') confines a flow path (P, P', P'') for the nutrition (13), and wherein the feeding device (1, 1', 1'') is at least partially deformable. The feeding device is characterized in that a nutritional additive (7, 7', 7'') is adhered to the flow path confining inner surface (6, 6', 6'') of the feeding device (1, 1', 1'') such that the nutritional additive (7, 7', 7'') is mechanically segregated from the inner surface (6, 6', 6'') when the feeding device (1, 1', 1'') is deformed.
