I'll just fill you in quickly with a brief history, actually maybe quite long 
I was bf lo up to 4 weeks, we were doing OK, had the usual problems like wanting to feed all the time etc. But I gave up sadly because I became quite unwell with an internal infection,my body was so hot with a temp my milk was like cottage cheese (sorry), I was on various antibiotics whilst continuing to bf but they where making lo very unsettled (hv said she was shocked I'd kept going with bf).
Anyway I moved her onto formula, Aptamil at first and then due to reflux symptoms onto comfort. My ds1 had reflux and even now has childhood reflux and is on ranitatine (sp!!!) so I know the signs to look for, she was still being sick, very mucusy and rattly so we took her to the GP who gave her infant Gaviscon, but this made her so constipated it made her little bottom bleed, so I have stopped this straight away.
I have also tried SMA Staydown, but she doesn't like the taste, I know I could ask for Enfamil but not sure if it will just be like the SMA. I'm also worried about making her even more constipated.
I'm now thinking back to when I bf and cannot remember a problem with sick or mucus. I'm still on antibiotics 9 weeks later, Cefalexin, actually does anyone know if you can bf on this? I have until Thursday and then go for another checkup to see if its finally gone.
I'm wondering if I started to pump now, could I build up my supply (I still have some milk). Would bf help me with the reflux or should I try another formula? I really don't want to put her on meds.
I could lower the dose of the gaviscon but worry about the salt content also.
Also can comfort (thickened milk) make reflux worse?
Sorry for all the questions, in a bit of a pickle with it all.
