Hi! 😊
Yes – The Medela Pacifier S 0–3 months (2-pack) fits very well with Medela bottles, also in 150 ml and 250 ml sizes, as they are made specifically for these bottles.
If you have the Calma system, these pacifiers also work without issues on the same bottles.
So you don’t need to buy pacifiers labeled «Calma» – these S pacifiers fit perfectly as bottle pacifiers for all Medela bottles. Feel free to let me know if you have questions about different flow levels or need to plan feeding according to age! 😊
Contact me if you have more questions💌
