I remember reading that when a baby has colic they often can't distinguish the feeling between hunger, so perhaps he is feeding lots when he has colic because he "thinks" he is hungry...? Also, like you mentioned, I think feeding also soothes the colic as well. I'm pretty sure it helped with DS when he was a bub. DS also fed 1-2 hourly around the clock, but thankfully I didn't have a toddler at the same time. DD is still feeding at least 3 hourly around the clock, but I'm lucky that she is a really quick feeder. I really hope things improve for you soon! Can you try something like Infant's Friend to try to soothe the colic? I even went on from that to Infacol for a while to ease DS's discomfort.
