My little guy was colicky around one month. If you're breastfeeding call a breastfeeding clinic. They really helped me. Apparently the first little bit of milk that comes out can cause discomfort because it is more sugary than fatty. I expressed milk before feeding him, and it actually helped a lot
my bro was extremely colicky and my mom would hold him like a football belly down with his face on the inside of her elbow area and her hand between his legs holding his bottom area. and other hand supporting back and neck and then would walk and bounce threw the house.
