How do you tell if your child has colic? In doing research, I found that it isn't considered colic if they cry less than 3 (aff) hours straight for more than 3 (aff) days a week. However, Will does have these symptoms: draws his legs to his belly, becomes red in the face, passes gas a lot, and has difficulty staying asleep. The only way he sleeps for any amount of time is if we let him sleep on us. However, he does not cry for 3 hours a night straight. We are more at the hour mark.
