Described herein are inserts for reducing sloshing in a bottle. The insert may be integrally formed in an outer shell of the bottle or removably insertable into the outer shell. The insert may include an elongate body extending between a first end opposite a second end; and an aperture defined by the elongate body and extending longitudinally through the elongate body between the first and second ends. The elongate body has an uncompressed state when removed from an outer shell and a compressed state when positioned in the outer shell. A diameter of the elongate body in the compressed state is less than or equal to a smallest diameter of the liquid retention compartment. The insert has a durometer between about 40 A and about 70 A. A volume of the insert is less than about 10% of a volume defined by the outer shell. The insert includes a compressible mesh material.

An apparatus may include an insert configured to be positioned between a nipple and an opening of a bottle when the nipple is mounted to the bottle. The insert is configured to facilitate airflow out of the bottle and through an interface between the nipple and the bottle when the nipple is dispensing fluid from within the bottle. A system may include a nipple, the insert, and a bottle with an opening. A method may include providing the insert, and positioning the insert between a nipple and an opening of a bottle when the nipple is mounted to the bottle.

An automatic pushing type complementary food device comprising a clamping body, an elastic member and a colander, wherein the inner side of the clamping body is connected to one end of an elastic member in a clamped manner, the outer side of the clamping body is connected to the colander in a clamped manner, the other end of the elastic member extends into the colander, a complementary food cavity is provided in the colander, and overflow holes are provided in the outer wall of the colander. The automatic pushing type complementary food device is simple in structure, convenient to operate, capable of automatically pushing and collecting complementary food when a baby uses the device, free of auxiliary operation by a mother, capable of bringing convenience to the mother during feeding, and capable of achieving automatic collection of the complementary food without a complex pushing structure.

A feeding bottle (100) including a reservoir (105) for receiving a liquid for feeding, a teat (115) for providing the liquid from the reservoir (105), a regulator (120) disposed between the reservoir (105) and the teat (115), the regulator (120) shaped to engage the teat (115), and a collar (110) configured to retain the teat (115) to the reservoir (105), wherein the collar (110) is adjustably movable relative to the reservoir (105), wherein movement of the collar (110) relative to the reservoir (105) moves the teat (115) relative to the regulator (120) which provides adjustable flow of liquid from the reservoir (105) through the regulator (120) to the teat (115).

A nursing bottle having an air returning function comprises a bottle body, a fixing cover, a nipple, a ventilation component, an air conduit, an elastic one-way valve set at a second opening of the air conduit and is located at the interior of the air conduit, a mounting part located on the second opening of the air conduit to secure the elastic one-way valve. The ventilation component, the air conduit, the elastic one-way valve and the mounting part form a gas returning device and are located on the interior of the bottle. The bottle reduces the contacting area between the air and the milk, lowering the amount of vitamin loss. The phenomenon of vomiting milk, choking and flatulence will be omitted since no air bubble is generated.
