Does the Bionix Controlled Flow Baby Feeder work for babies without a strong suck?
In order to feed on the Bionix Controlled Flow Baby Feeder, the baby must be able to suck with enough force to overcome the restrictions imposed by the flow restrictor and the walls of the channel in the nipple. If you do not believe that the baby can suck with enough force, it may be best to use the Controlled Flow Baby Feeder at a higher flow setting or to thin the formula.
