Colic?

Mia cried (okay, screamed) yesterday from 1:00 p.m. until 5:00, when I finally just held her and allowed her to sleep in my arms for an hour. Today the crying began at 10:00 a.m. and I'm crossing my fingers that it's now stopped for the day. I've been trying the usual soothing methods, like gas drops and swaddling. I've also been trying the 5 S's (Dr. Karp), and they work for a few minutes, then she's back to crying. Today I tried the sleeping-in-my-arms thing again, but no luck. This last time I used the hair dryer to quiet her and then turned on this stuffed animal Robyn and Kenny gave us that plays different soothing noises: a heartbeat, rain, the ocean and a whale. I have it on the ocean right now and she's been asleep for about 20 minutes. Today has been a bit stressful, but if it goes like yesterday, I will at least get a good night's sleep tonight. Wish me luck. Oh, there she is. Guess I'll keep trying.
