Really need some advice. My 12 week old dd has been diagnosed with silent reflux last week and is on gaviscon in her normal cow & gate milk which seems to be helping a bit but is already making her quite constipated. I've tried her on SMA staydown but she seems to hate the thicker texture of the milk. Is there any other milk that is thinner but better for her. she is still screaming randomly, bubbling at the mouth and very congested. help!!
