Less AI2s?

Alana • Las Vegan, early-thirties mama of 2 boys
Maybe I'm not looking properly, but I'm having issues locating AI2 diapers. Not all brands will call it that and I'm struggling with the names! Is it that (A) AI2s are not a good option hence less popular? (B) They are just not called AI2s. They're called... Or (C) something I haven't thought of?  Help please, mamas!
