Crying baby

Sandy

My baby is 6 weeks old and at first when we first brought her home she would only wake up maybe once at night to be fed. But now she is waking up every hour screaming and crying uncontrollably. My mom and sister tell me to jus Tyler her cry it out. But I feel like she may be hungry although when I do give in pick her up and feed her she doesn’t drink much and just keeps crying. Is this happening to anyone else?!
