Colic is usually defined by a continued crying for 1-2 hours at the same time of day/night over a period of several weeks (can be every day but has to be at least like 3-4 days a week). That is what we were told when our older son was a baby. There is no explanation and usually there is no real way to comfort a colicky baby. If the formula is the culprit than it's probably not true colic. My son had it and would start crying at 11pm every night like clockwork. It was completely independent of his eating schedule (whether he was hungry or just fed, just slept or was tired, etc). He would just wail from 11pm-2am every single night and then, like a switch being tripped, he would stop at 2am and fall asleep. Nothing comforted him, although he seemed to like when I bounced him on my knee. It was exhausting. He outgrew it at 3 months.
