Medela Calma Bottle, 150ml

Product information

Introducing the revolutionary breastfeeding friendly feeding solution for breastmilk. Calma is the only scientific based feeding device that helps to support the similar sucking behaviour of the baby at the breast. Calma is the unique teat for babies who are being breastfed with breastmilk, as it allows them to suck, swallow and breathe, as learned on the breast.

Calma requires a similar sucking behaviour to breastfeeding using the tongue to create a vacuum making it easier for babies to switch between breast and Calma. It's the first and only teat to be introduced during breastfeeding to support the similar sucking behaviour of the baby at the breast.

Please note: Breastfeeding needs to be well established before introducing Calma. Calma is recommended for breastfed babies and not those who are currently bottle fed as they may find it difficult to feed.

The bottle is made from BPA free materials.

Q & As

Medela Calma Bottle, 150ml 3.5 5 4 4
Brilliant product I have had lots of trouble getting breastfeeding established due to mastitis and this bottle really helped baby getting on with expressed milk. It has not affected the latch and baby was able to switch between this bottle and the breast without any issues. Still using it after 3 months when leaving baby with daddy. It's definitely more expensive than others, but using it meant that I could get breastfeeding established. Would definitely recommend it. 16 January 2015
Good suck, but leaks These are great for keeping baby's suck strong so they continue to breast feed but given how much these cost each (I have 8 of them!) I which they'd sort out the leaking. Some are better than others but if you buy them, make sure you store them in a plastic bag when out and about else you may end up with a pocket full of milk. And yes, the pieces are always secured correctly because I check carefully. They leak when the right way up. It's odd and irritating but I put up with it because I've yet to find a teat that is as good for baby's suck. 29 October 2013
Great Procduct I have a 5 month old little girl who is solely breastfed and I use this bottle if I have to leave her with my husband or sister. She has used it since 3 weeks old and has no problems with it. Her latch has been unaffected too which was my initial concern. Although slightly more expensive than the other bottles you only need the one teat all the way through until they are weaned, so it works out to be a good price overall. Would highly recommend. 03 July 2012
poor design the teat doesnt securely fit, milk leaks from lid and clear plastic lid doesnt waste of money 11 October 2011
