What teats and flow are you using. I add one scoop to a bottle of 5 floz and shake really well but never to a boiling hot bottle or it goes like thick lumpy paste. I use perfect prep and put in at the end. Shake and wait 5 mins then shake well again. Not sure about similac but my girl is under 3 paediatric docs ( a normal one a gastroenterologist and a respiratory specialist) she suffers what they class as severe reflux screams more than she doesn't round the clock, arches back refuses to feed and is sick a lot. We have just had to have a chest x ray a few weeks back as she is aspirating her milk into her lungs. She's on ranitidine , lanzoprazole, gaviscon, carobel, neocate, movicol and just been referred for a medication called ketotifen. She's has severe eczema and needs allergy testing now too and has a condition called laryngomalacia, has respiratory distress from it and well my life is like living hell right now. I'm up every 2 hours round the clock with her screaming feeding and vomiting with no end in sight. The new meds seemed to help for 1 week now I'm back to square one and it sucks. I've been through the cmpa with two of my others but Olivia is something else entirely 😭if I can offer any advice please ask but it sucks

Have you changed teat size? I had this issue and then changed to vari flow and it helped x
