I need help. DD is now 6 weeks old. For the past 2 weeks now she gets fussy and irritable at the same time every night which is usually between 9-11 pm and the crying goes on for about 2 hours straight, maybe more. I don't know what to do for her. She cries for basically no reason.

She will have a bottle, be changed, a pacifer does not work, swing doesn't work, talking and playing with her doesn't work. The only thing I can do is walk around with her, bounce her, or rock her and sometimes that doesn't even help. I don't know what to do, its exhausting. I even try playing music for her but that only lasts a few minutes before she starts crying again. Even on her bath nights she gets this way and the bath used to calm her down. The rest of the day she is pretty good baby.
Is this considered colicky? I don't know what to do. Is this just something she will grow out of. I wish I knew why she was crying.
Thanks ladies.
