Hi,
I understand how you feel. When my youngest had colic, my mom gave him a few infant drops in some warm water, laid him across her knees and did a gentle pat and rock to help the gas. Also during this time, she would sing a little song to him because he was so uncomfortable. Then we tried what we only knew to do, if it is colic for what seemed like forever, my husband would put on a undershirt and have the baby close to his chest, then he would pray like he was building a kingdom; during the span of time we would sing songs from our childhood. We also did alot of pacing around the house to find a comfortable rhythm for him.
After that, when he was irritable, we would do the same, and it worked.
