FTM here so bear with me. I was gifted a bunch of Avent bottles along with adapter rings. I have not been using adapter rings but received those as well. Should I be using them? Baby seems to be feeding fine without...
I assume you have the Avent Clasic and you mean the little blue ring that fits inside the bottle? That prevents leaks- can't believe you haven't experienced any yet? We'd both end up soaked w/o that ring! The Avent Naturals don't need the blue ring.
