Medela Calma Bottle Nipple and Collection Bottles, Made without BPA, Air-Vent System, 8oz / 250mL

I use this bottle all the time the first 6 months, it helped me a lot the baby has to sucks in order to have the milk so recreate the mimic from breastfeeding he was definitely not confused with the nipple and not that desperate bc the flow was not fast enough. It is also great for the transition.

My son had a few complications out of the gate that made breastfeeding hard for him. While he loved to guzzle from his bottles, even those that were labeled breastfeeding-friendly, he resisted breastfeeding at every turn. In near desperation, I tried this nipple. He hated it!! We had finally found something that was HARDER than nursing (or at least not easier). For the first time, he turned away from a bottle and rooted against ME. Though our breastfeeding journey continued to be rocky for a while, this nipple was the start of things getting better. He did learn to use it, and once I returned to work, he switched happily between bottles and nursing. Due to severe reflex, his GI specialist recommended adding rice cereal to his bottles. We did notice the nipple occasionally became clogged and needed to be rinsed our mid-feeding, but it wasn't a huge issue. I didn't have any trouble with leaks or deterioration, either. One final note: the inside of the nipple looks like the frosting of a lemon sandwich cookie. In the exhaustion and delirium of the newborn days, that was oddly amusing and comforting.

I bought two sets when we were expecting. I've been BF since birth and have been able to share the experience of feeding our baby boy with my husband and other caregivers for more rest for me during a difficult recovery and he has never had any trouble switching from breast to bottle and back again. The only flaw I have found is that the cap for the nipple doesn't secure down well. I've made bottles and put the cap over the nipple only for them to fall right off while packing. Please make the caps able to snap and lock onto the top of the bottle for easier transport.

I bought these for my son when he was a few months old and I was transitioning back to work. BEST DECISION EVER!!! When assembled correctly these nipples do not leak. The only time they started leaking was when my son had chewed up the nipples once he started getting teeth - but that is not the products fault considering that chewing any nipple would cause the same issue. It is the only nipple my son will take to this day (he turns three Sunday so no more bottle for him). Prior to finding Calma I bought a lot of different nipples only to have each one summarily rejected by my son. Once I found this I knew it was it. He loved it immediately. I have used these nipples from a few months to three...I have NO COMPLAINTS. I just recommended them to my boss and have recommended them to every Mama I know. If I have another child - which I am praying for - I will only use Calma again. All other nipples are a waste of money. I do think you can help mamas out by at least offering more bottles with the nipples, because they are pricey...but even with that being said, I have no regrets and will/would obviously purchase them again. Great product! Thanks Medela.

I bought several calma bottles and nipples in the beginning thinking they would prevent nipple confusion while I worked on bringing in my breastmilk. Unfortunately no man made product will be exactly like a mother's nipple so after a while, my baby would only take the bottle. Then they started to leak. The collars seem to crack over time and the airlock breaks. I've tried several times to switch my baby to other bottles but he will only take these. So I'm stuck spending a ridiculous amount of money on bottles and nipples that I know will eventually spill milk all over the place. It's the most annoying feeling to be half awake in the middle of the night feeding your baby and as you take the bottle from his mouth and stand it upright, it soaks your hand and shirt in milk. Frustrating.
