has anyone used the new avent natural bottles? I've seen them advertised online but haven't found them in store anywhere to have a good look at. They are meant to be better than the standard teats, more natural closer to nipple. I'd like to get any feedback on:
- babies transition to these bottles from breast, latching on etc
- any colic/reflux issues
- leakage? (I find the standard bottles leak quite badly)
- if they are compatible with the steriliser and bottle warmer that is used with the standard avent bottles. Are they a different width? Wider neck?
