A nipple (11) for a bottle assembly (1) includes a flow control valve (68) configured to open when subjected to a first vacuum pressure and to close when subjected to a second vacuum pressure that is substantially the same as or less than the first vacuum pressure. The flow control valve is configured to maintain the flow rate through the nipple between approximately 7 milliliters per minute and approximately 15 milliliters per minute.
