For dummies - the ONLY one he has ever happily sucked on is a cherry shape - either happy baby or tomee tippee interchangeably

For bottles - I gave Fergus EBM for 14 months and the ONLY teat he has ever happily and consistently drank from is the pigeon peristaltic (wide neck). I used these teats in either pigeon or avent bottles. We had this teat recommended by a number of lactation consultants and speech therapists for use when breastfeeding. Not sure whether I agree though, given my only experience of these things is with Fergus - a notoriously fussy feeder!
