These bottles where invented by
a doctor and tested on his children. Unlike all
other bottles these bottles do not form a vacuum
in the bottle while baby is feeding. Since the
bottle does not have to vent air through the
milk or formula it prevents the tiny air bubbles
from forming inside the milk and formula. This
design also prevents nipple collapse for a more
natural steady feeding and since baby doesn't
need to suckle so hard it helps reduce fluid in
the ear. These are the best bottles you
can buy and now they are the best priced as
well!
