My nearly 6 week old screams all day and into the night, I believe it's bad colic, she's on colic formula, tried gripe water, infacol, infants friends, i purchased dr browns bottles ( she won't take them) I'm lost as to what to try now, it's really upsetting, I've seen the doctor she said to try new formula... Done that, she's best on colic one but still screams and screams and screams!!! I'm really lost as to what to try now, the constant crying all day and night is torture!!! Any advice would be great!!
