Silent reflux (6 weeks old)

Coco

EBF baby, I think he has this...🤔☹️ hes super squirmy when he feeds, pushes away as he nurses, as well as unlatches.. I’ve noticed milk in his mouth, in between feeds... won’t stay asleep for long, without squirming... sometimes gives a quick cry when nursing, almost as if frustrated.. gets hiccups often... just posting in case someone can relate.. will be contacting his pediatrician, to see if I should do something? New to me, so I have no clue..is it something I’m eating? That’s causing it? (He doesn’t cry too often, but does seem uncomfortable when he nurses)
