LO is 10 days old.  For the past 5 nights, she cries and fusses for many hours.  It usually starts @ 5-6 and goes on until 1-2, sometimes later.  We have tried everything to calm her - swaddling, swinging, crying it out, gas drops, pacing the house for hours with her, putting her in the car and driving around.  It is so incredibly frustrating.  Everything I have read about colic says that it usually starts around 2-3 weeks but this started when she was a week old and is Every. Freaking. Night.  She'll settle down for a few minutes at a time but then goes right back to screaming.  She is formula fed and has plenty of wet diapers and usually 2-3 dirty diapers everyday so I don't think it is constipation.  She goes back to the pedi on Monday so I will ask about it then.  There's really no point to this post other than for me to just vent my frustration with the situation and see if anyone else has a similar issue with their LO and has found something that helps.

I'm sorry you're dealing with this though, it is so frustrating!
I agree that you might try a different type of formula.
