I have a friend at church who has a 4-month old girl. From about 1 month old, she's been crying all day long. It's gotten a little bit better in the last month, but she still has many periods where she literally screams from the top of her lungs for very long minutes, even hours. Her parents think she is just high-needs and haven't checked her for any problems. Are high-needs baby like that? Or could she have something else. I really feel for them, it's really hard to see their dd cry all the time and they are exhausted.
