There is some information missing. For instance, do you breast feed or bottle feed?
Have you spoken to your Pediatrician, and if so, what recommendations were made?
The first thing to do is to contact and discuss this with your Pediatrician to make sure it is colick.
Next would be to adjust your diet if you are BF or adjust your baby's formula under the guidance of your Pediatrician.
I had to stop breastfeeding to rule out food allergies. Even formula did not help much until and we had to try 4 different ones. My Ped finally diagnosed my son with acid reflux and gave him medicine which helped some.
What I also found helpful, was for my son to sleep more upright (he slept in his bouncy chair or car seat), and husband and I took turns trying to soothe him,
If you have someone that can help you out at anytime, reach out to them, Just taking a break for an hour was very helpful.
His symptoms did ease by 12 weeks.
Hope your baby finds some relief so that you can too!
Good luck!
