Crying during feeding

Recently my LO has been crying during his feeding. He’s clearly hungry but when I put the bottle in his mouth he sucks a few times and starts to cry. I don’t think it’s gas cause he does it even at the beginning of the feeding. Also he hasn’t been finishing his usual amount instead he will fall asleep at the bottle or stay awake and just suck on his hand. He’s 2 months 1weeks and I’m just at a loss as to what it could be. Any one relate or have any idea?
