It usually peaks around 6 weeks, and lasts until about 3-4 mo. Most babies are over it by 5 or 6 mo. at the latest. If it's actually reflux (rather than colic symptoms with unknown causes), then it will probably improve by 5-6 months after the baby starts on solid foods, but some kids continue to have problems as they get older. My DS has a mild case of reflux--never medicated him, just gave him smaller quantities of food more often and tried to keep him upright after eating. He was much less fussy after 6 mo., but he still has some trouble even now. I could hear the acid coming up in his chest after he ate sometimes, so I imagine it feels a lot like heartburn does to an adult. :-( Those first months are pretty rough if they have colic or reflux, but it should get better within a few months. Hope you have someone to give you breaks and help you out. I'm thankful we lived near my mom to help us get through that time.
