Hi there, we have soooo been there, with a reflux lo. She had a bottle phobia from 3 months up till around 11 months, so have no advice, as nothing we did worked, but lots of hugs from me.
We did find she prefered a cup for a little while. You can try this as well even now. Also when the time comes for solid, you could give things such as yoghurt to help.. Also if she is still fussing when feeding are you sure she is correctly medicated ie: enough meds for her weight, you could check with the doc, but as I said, dd had the max meds and still hated the bottle. Ihad to take a step back, look at her weight gain and general help, as unfortunately there was nothing I could do about it. We also gve calcium and vit drops, could you get these from your doc?
hope this helps a little, I have been there and I know how frustrating this must be.
