Eh, this is such a good question, I actually heard about this from a few mums around me! My friend went to try the Dr Brown brand bottle and she said the Pigeon wide neck bottle top fits on it perfectly, and it's so much cheaper somemore, so she was super happy with that combo! Someone in my mum WhatsApp group also mentioned that as long as the bottle is wide neck, the Pigeon Softouch teat should fit, so that's the key thing to look out for when you're shopping around.
