My lo gonna be 5 months soon but from couple of weeks she is been too much aggressive and screams whenever I try to feed her, she is been EBF but whenever I try to offer her she just starts screaming and cries her lung out and if I don't give her she is fine can be without feed for 4-5 hrs, otherwise she is perfectly fine and playful. Also it looks like she is teething as she chews her theether as if she will eat.  Don't know what to do to feed her. Pls hep
