Q: will this work with bellababy?

no. for bellabay, please buy from the following https://www.amazon.com/Maymom-Compatible-Bellababy-Double-Electric/dp/B09W2KRSC5/ref=sr_1_2?crid=23GCK9QCNBTGZ&keywords=maymom%2Bbellababy&qid=1676120494&sprefix=maymom%2Bbella%2Caps%2C298&sr=8-2&th=1

Q: Did anyone have trouble and feel like these ran big?

Yes I definitely felt these ran big as compared to standard spectra. It doesn’t make sense but 19mm was too big when it was the right size in spectra

Q: I used mine before realizing it’s the wrong flange size, should I still return them?

I did the same thing. I just brought flange inserts that were my nipple size and just pushed it in for the correct sizing. But you can if you want.

Q: Does this flange work with the Kiinde system?

Yes if you have the Kiinde adapters
