Hi everyone! Maybe I should clarify,
Dr Brown bottles are the Best (wide neck or standard) My Dd likes both, however she seems to take the standard nipple better (she doesn't make as much noise with the standard). I have tried almost all the popular brands, and Dr Browns seem to be the BEST!
By the way, my bottles never leak, I warm them in a bottle warmer (with the insert inside) but I take the top off while I am warming them, and it works great!
As far as the kind of nipple (it;s personal choice, if you already have the wide neck or standard and your dd/ds likes it then no need to change it
Good luck to you!
