I solely feed my almost-4 month old expressed milk (trouble latching at birth and now I'm back to work). She's been great with feeding and sleeping until about a week ago. About once a day she stiffens and cries inconsolably (sometimes it can last 20-30 minutes). She generally wears herself out crying and goes to sleep. Either during her nap or shortly after she passes a lot of gas. I'm trying gas drops at each feeding and massages. This seems to help a little. I've also tried gripe water, but it's black and creeps me out. I've cut dairy out of my diet for 3-4 days. From what I've read on different forums the gas is somewhat normal due to immature digestive systems. My baby was born at 37 wks (like her older brother), but I don't know why it's starting now and didn't happen earlier. Is there anything else I can do to ease her pain? Is switching to formula designed for gassy babies a good idea? My daycare provider said she's never seen a gassier baby or one that is so affected by gas. Should I have her examined? Please help!
