Reflux or something else?

[Brambblee]

I have a 14 week dd who was 5 weeks prem, pathological jaundice so 11 days with a feeding tube. Also tongue tie. Came home and jaundice peaked again at 5 weeks readmitted to hospital due to poor feeding they put it down reflux and tongue tie and gave carabel for a breastfed baby (we have previously tried gaviscon). Finally got tongue Untied at 8 weeks feeding improved but still terrible wind and sickness. Got moved onto omezeoprazole which helps a little. But now she has been getting worse sick during and after feeds up to an hour or more after as well. Also gets terrible wind which causes her so much distress and is inconsolable during episodes. She is a happy little thing when not in pain, but it is ruining her happiness atm and disturbing her sleep as she cries out I pain when sleeping. Was referred back to consultant last week who decided it could be cow's milk protein. She is breastfed and I have cut all dairy, I know it's only a few days in and it can take 6 weeks to clear but there seems to be no change and if anything she is getting worse. She also has a umbilical hernia, which I am told is fine.
Has anyone any advice or thoughts of what is causing it or what I should be pushing for? Thanks

Have you also removed soya? If you haven't I would cut out high levels of soya such as meat and dairy replacements as half of babies are allergic to both.
My daughter has multiple food allergies and reflux. She has needed a lot of medication to control the reflux - top dose of omperazole plus thickener (gaviscon) and domperidone. For a while she needed a stool softener too because of the gaviscon. I would start a food diary to see if there are any correlations. If it's just dairy and soya you won't need them but if it's more you don't have to wait to gather the data to help identify other allergens. My daughter only got a benefit from the omperazole at the highest (3 mg/kg) dose our GP was only increasing her dose with weight and not moving her to higher doses when it wasn't helping we had to see a paediatrician for something else and he sorted out her omperazole dose.
