It's suppose to aid colic and reflux babies but also be better in reducing lazy feeding. The baby has to suck the teat to get milk (they don't recommend using it for formula) the same way they would have to suck at the breast. If you tip a bottle upside down with a calma teat in it, the milk won't come out (in theory). Do because its not free flowing, they say that the baby is less likely to become a lazy feeder and therefore it's good for those wanting to combine feed (bottle and breast) or who can't breast feed for whatever reason but want to return to it down the track.

Because the baby controls the feed flow, it's suppose to be better for colic and reflux compared to free flow teats.


We tried my reflux baby on it (it came with the bottle and we were trying to get her to take both bottle and breast for various reasons) but she struggled with it. It seemed much harder for her to get milk from the bottle than the breast...so she refused the bottle if she knew I was around. I also felt that she sucked a lot of air in with it - therefore not helping her colic.

The theory is good. I just haven't been successful with it here.
