At my hospital we have found the haberman feeder to be a useful tool in
feeding babies with tone problems and  coordination problems. The ability to
adjust the flow is the part of it that is so unique. It requires close
observation from the feeder, however. I have a poster that I place close to
the baby's station so that nurses have information on it if they haven't used
it before.  Maybe the fact that it varies is one of the reasons it can be
useful with the baby who is learning the breast as well. The infant must
learn to participate, and learns that the milk flow is not always constant,
as with breastfeeding.
