Try sticking to one for a day to see what's bothering him.. It could be what you're eating or the formula isn't working for him. Or it's gas, try gas drops and bicycles with his legs
I check his diaper, see if he wants to nurse, rub his tummy or try to burp him. One of my boobs has a heavier let down so sometimes he fusses about that so I'll hand express then put him back on
