As far as I knew, the small bottle has the size 0 which I’m sure is the smallest xx
It should be 0+ (which is slow but not super slow)
Rather than change the size, try making her take breaks, that's what we do. As far as I know, the size is too big when they sputter and the milk overflows
Ours is size 1 (also the free Boots MAM bottle). We have since changed to 0 and my baby was also guzzling it too quick
@Charlie found it! Thank you
@Giorgia we’ve tried but then she just gets angry and guzzles even more. She does tend to sputter a bit too so my guess is it’s too fast for her
All of mine were 1 i had to buy size 0 teats
https://amzn.eu/d/e6FaIWk I was recommended these to help reduce air going in and to be slower than mam. They apparently work with the mam bottles. Mine arrive today
There should be a number on the teat. The side opposite the MAM logo
