Hi - we saw a peaditritian at yorkhill yesterday for my babies constant screaming, refusing to feed. he is 14 weeks. she sure he has silent reflux, after lots of tests and we now using infant gaviscon. just wondered if anyone has any tips on bottles or formula. currently on avent with 3 flow teat and aptamil. is it worth changing bottles or the milk???? would this help???tried dr brown when he was younger but teat was too soft - many thanks
