In conventional feeders, much of the baby's effort is wasted on compression of air within the bottle and movement of feed within the system. However, the unique Haberman teat is separated from the bottle by a one-way valve. Once filled, milk is held in the teat and cannot flow back into the bottle. all your baby's sucking effort is directed onto the contents of the teat, so even the weakest suck gets results.
The Haberman Feeder has a slit-valve in the mouthpiece which only opens when your baby sucks. Your baby has complete control and is never overwhelmed. It also has the advantage of variable flow. Graduation from a large opening, down to a shut position, can be achieved to suit the indivdual needs of your baby. Whichever opening you select, it will always shut between sucks.
Many babies swallow air whilst using ordinary feeders. This is because a vaccum builds up inside the system and the baby must release his lips from the teat to allow air back in. Consequently, air is swallowed with the next mouthful of feed causing wind, vomiting and colic. The Haberman Feeder reduces air-swallowing. It has a special air inlet groove which allows air in at the same rate as feed is released from the system. There is no vaccum to work against you baby's sucking efforts and air-swallowing is avoided. Even babies with cleft palates benefit significantly from this feature.
If your baby needs some additional help, you can gently squeeze and release the reservoir of the teat. This will deliver a controlled amount of feed into your baby's mouth. The full teat has a natural resistance which prevents you from squeezing too hard.
