colicky baby

I read colic is usually determined after 3 weeks, but I'm 95% sure my baby is colicky. He has everything he needs, but will still continue to cry for no reason. He will be 2 weeks old on Tuesday. Part of it may be his tummy hurts, but he stays up for hours between naps fussing and crying. He was up for about 7 hours today and fussed just about the entire time. I'm currently trying to get him down to sleep and every time the book falls out of his mouth he wakes up and cries 😩.
