Sometimes baby are not hungry but they show hungry cues probably because they just wana “suck” on something for comfort. I feed my baby 100ML and he sleeps for around 2 hours then wakes up and shows hunger cues I just feed him another 10-20ML and he knocks out. I think it’s also part of growth spurt or the previous milk fed to him was too “thin” hence digested faster and needs alil more milk
I would carry her for feeling, but without waking her up. Continue to carry her for 5~10mins after feeding instead of burping.
