Colic?

The last few days Lincoln's been extremely uncomfortable after feeds, spitting up his milk, scrunching his face, crying until he's red and drawing his legs up, tensing his body. I've found a few times holding him high up on my shoulder has helped a little to settle him but its not a feasible method to use continuously. Friends have advised it sounds like he's suffering from acid reflux.

I'm surprised because its less common for breast-fed babies to have this problem, and we've tried burping him after feeds to help but whether or not he does burp it's not made much difference. I absolutely hate seeing Lincoln screaming in discomfort, I know how awful heartburn feels from being pregnant with him and it's not fair that such a small little human should suffer from that pain.

I've bought some infant colic drops, DENTINOX, which are suitable to give from birth but I've not been 100% sure on giving them to him. Natural methods like burping, massage and rocking haven't been helping at all and I'm worried about it getting worse because its putting him off his feeds, making latching him on harder.

I'm concerned he will lose weight if he keeps spitting up milk, even though the internet says baby spit-up looks more than it actually is, I can't help thinking it still seems a lot when his tummy is so small. Hopefully it wont last, they say it would be much worse if he was bottle feeding, so I've definitely found a renewed dedication to breast feeding. Even at times when I'm irritable and feeling a bit like he's never off my boob, I know I'm doing the best thing for him and it makes me happy to know I have it in me to not give it up.
