I bought both the tommee tippee closer to nature and Avent although I didn't b/f they are both great we stopped using the tommee tippee as he would suck the teat to pieces

the midwives at our hospital went and on and on about using these bottles, but really in the long run some babies wont like the teat etc, I have one friends whose baby will only use PUR teats so therefore needs the narrow bottles etc
