6 month old breast feeding

Alexus

My 6 month old gets fussy while being on the breast he latches on and for literally 1 min and then he gets fussy and starts crying and screaming . At some point I thought I wasn’t producing any milk for him but when I push my boob out milk squirts out . Idk what’s going on with him at the moment because he is also being very clingy towards he lately but very fussy .
