Every time we try to feed my son he fights his bottle. He hits it and smacks it out of his mouth and screams and cries and it's impossible to feed him.. it's really frustrating because he's hungry but just won't let the bottle stay in his mouth. It's a constant battle to feed him.. Eventually he eats but getting him to is a nightmare. He's had 2 teeth for about 2 months now so I don't think they hurt him still? What could be wrong with him. Also he isn't gassy his formula helps him burp really well.
