I don’t think it makes a difference (and if you loosen it too much, I can see spillage happening). You can choose teats that will change the milk flow if you need to.

I always thought this would increase the air that’s swallowed, increasing wind. Also making it flow too fast and swallowing too much wind

Yes. It helps get air bubbles into the bottle so they don’t “suck the guts out of it” so to speak.

I have heard this too, you have to get the balance right or the bottle leaks everywhere.

IT WAS ALSO SIZE OF TEAT HOLE SOME WERE TOO SMALL AND HAD TO MAKE THEM BIT BIGGER.TRY BOTH AND SEE.

I never have? I would imagine the bottle could leak.m

This is true however don’t loosen it too much!

How was it?

I used Avent bottles & yes you do need to loosen just slightly to assist flow.

What did you end up doing?

did you end up trying it?

Did you try it and did it work?

I’ve never heard of this but I used avent bottles and you buy different teats for different flow

Did you end up loosening the cap on the babies bottle?

Yes just a little

Never actually heard of doing that.

I think adjusting it depends on the bottle I think, plus how well your baby can suck it .

I have never used a bottle so its good to know these things awesome thanks I learnt something new today

Yes that is actually true. I use to loosen bottles. U don’t need to loosen much though

yes I did this with a few brands
