Hi all.
First post! Purchased 6 Dr Brown options + bottles. Turns out 3 of them are the old style "original" and 3 are the wide neck version.
We've since moved up a teat size for LO and the shops only sell wide neck options and we can't get any size 2's for the original style.
The main issue is the new teats don't fit the original collars. So, long story short, does anyone know where I can find wide neck collars?! I've looked online but can only find original sizes. Even those advertised as wide neck look to be the original style 
Any help massively appreciated!
