I used the Dr Browns with DS1 when he was a colicky baby and they def seemed to help. Have started DS2 off on the basic Tommee Tippee "closer to nature" ones (as they were cheaper) but he seems to get v windy.
I spotted that they do a more expensive "anti colic" range and wondered if I should upgrade to that if they're any good as DS2 has already got the hang of the teat shape, or if I should just bin it and go straight back to the fiddliness and expense that is Dr B?
