My daughter is a week away from turning 4 months and has just started screaming. She used to be a great sleeper and fairly quiet. Now periodically she screams as if in pain. Nothing seems to be the trigger. It happens while eating or two hours after eating. While doing tummy time or standing. In the morning and the evening. It even happens when she is sitting alone somewhere and nothing about her environment has changed. Nothing seems to calm her. She also will suddenly stop crying.

Any thoughts or suggestions? I want to take her to the doctor but my husband keeps insisting it is nothing or that she is teething.
