Alex is almost 10 weeks old and over the last 5...

Alex is almost 10 weeks old and over the last 5 weeks he has been getting wind. I have tried sitting him upright to feed, taking him off the breast and burping him regularly. I have also tried gripe water, Brauers colic relief, infacol & infants friend. The last 2 weeks he has got worse & wakes up screaming early morning & isnt settling throughout the day. He does get some relief when he passes wind but it isnt long before the next pain sets in. I have heard that everything will be better at 3 months but that feels like forever, especially when I see the pain he's in. Any suggestions appreciated
