Usually in the evenings but also at random times, my baby will cry when offered the breast. I know he's hungry because I see him smacking his lips. But once I try to put him on, he will cry. We will fight each other for a bit, he might shake his head back and forth, root and almost latch but then cry, push me away, and eventually when I have my nipple in his open crying mouth, he will start sucking vigorously, like he's either given up or finally realized I am giving him exactly what he wanted. Is this normal fussing? I don't think it's flow or stomach issues since its before he starts eating. I also don't think it's bottle preference since he's ok for some nursings and not others. It's so frustrating because one second he acts hungry and the next he's refusing. What does he want?
