Seem very similar. DS had colic and it stopped dead on 3 months, but still regurgitated a lot of milk but it didn't distress him. With the colic he was in pain or discomfort 24/7 unless I carried, rocked, stroked his back, and he did the typical pulling his legs up. No milk allergy. He's a big teen now, but you never hear about colic, just reflux.
