Comfort milk vs hipp organic

[Kazups22]

Hi all. My 10 week old is currently on cow and gate comfort milk and has been since week 4 due to colicky symptoms as well as susupected silent reflux. (Dr advised comfort milk as its thicker rather than gaviscon which has caused less spit up) She has been fine on this up until few weeks ago where the symptoms have reappeared. Has anyone moved from comfort milk to hipp organic which ive heard good things about? Part of me wants to wait until the 'magic' 12 week mark but the other part is struggling with a fussy gassy baby. We are using dr brown bottles with size 2 teats and wondering if a, its worth switching and b, whats the consistency like?
Thanks
