My baby is 4.5 months old. I EBF for the first month but then he wasn't gaining enough weight and we had to top up with formula. I tried triple feeding and all kinds of pumping schedules to try boosting my supply. This was exhausting and mentally draining. At this point we realized that he had reflux and had to switch to AR formula. The baby suddenly decided he doesn't want my breast. I tried combo feeding with bottles (my milk + ar formula). I tried lots of things. Now i'm at a point where he mostly drinks formula and i pump once a day to keep my milk. Whenever i try to give him some, he spits most of it. Should i keep trying or am i just wasting my time and adding anxiety? I hoped i could breastfeed at least once per day but he doesn't tolerate my milk.
