OH you poor thing, I totally hear you with the med's. My Ds now 2, had silent reflux which began clearing up at around 8mths. I kept getting told it would go away when he was 6mths or when they begin solids but everytime we dropped the zantac that he was on or put his cot down flat again we'd start all the reflux problems again.
I think the worst part was at 4 mths I was still giving up to 8-10 breastfeeds a day. Changed to expressed B/milk and he was only taking 110-150ml per feed if that. He couldn't handle more than that. Even with formula, same.
It has to be one of the most frustrating illnesses. Just know that things will get better eventually. It's not going to be forever. I ended up stopping breastfeeding trying different formula's, thickener's etc. The thickener's only constipated him.
Hopefully your DD wont be on med's for too long after she begins solids, and sits up etc. Good luck with everything.
