Reflux gassy baby

Anyone else baby suffering from reflux? Any tips?

She also has a hard time passing gas and is in pain at times. Won't settle for sleep at night.

We're currently breastfeeding by bottle (has helped tremendously), burping half way and when finished. Then holding upright for 30-40 minutes.

Usually works but around the 3am and or 6am feeding is when she struggles the most.

Moms diet is strict: no dairy, no citrus fruits, no broccoli/cabbage/tomatoes/beans, no coffee, no caffeine.

I don't wish this on anyone. Sleep deprivation with a fussy baby is no joke.
