Q. Does the Dr Brown’s baby bottle really work?
A. Yes! When babies feed they suck liquid from the bottle through the teat. As the liquid leaves the bottle, air enters in through the vent into the feed. Our patented internal vent allows the air to enter and directs it to the area above the liquid, keeping the air and the liquid separate. Because there is no vacuum to inhibit the flow of liquid, babies can feed at their own pace. Click here to see how Dr Brown’s Feeding System works.
Q. Why is it good to prevent a vacuum from developing in the bottle?
A. There are two major problems associated with most traditional baby bottles: air and vacuum. Air ingested by babies can cause discomfort, sleepless nights and symptoms associated with colic. A vacuum in the bottle can transfer air to a baby’s middle ear and can encourage fluid to be drawn in. Traditional and restrictively vented bottles tend to develop vacuums when babies feed from them because babies need to suck progressively harder to get any liquid from them. Babies seal their lips to the teat when they nurse, but as the vacuum increases they ingest air through a weakened teat seal. Air enters the bottle through the vent in the teat and aerates the formula; this air is ingested.
Q. Is that a straw in the Dr Brown’s baby bottle?
A. No it is not a straw, it is a vent tube which is connected to a reservoir, and it’s the part that allows air to enter the bottles and be directed to the area above the liquid, keeping the air and the liquid separate
