LB suddenly won’t feed in my arms

My LB is 2 months and has always suffered with a bit of reflux, we do slow paced feeding and burp multiple times on feeds. The last 24 hours he’s been screaming when we hold him to feed him a bottle and was taking less. I tried feeding him in his bouncer today and he’s fed fine?! He’s still sat in it like he would be in my arms but will not take the bottle from me. I can hold him and give him his dummy but the second the bottle hits his lips, he screams. What the actual?! Please send advice 🙃😅
