Both of mine had colic. DS1 was the worst and even now at 7 years age his involuntary burps could still be shockingly massive and loud. So I think it must be the way his digestive system works...Windy.
DS2 is 8 months now. He was quite be until 3/4 months ish. I had been giving him Colief. Still not sure if it worked but it did appear if I stopped giving to him, the following days would have been a relapse.
Also I found most of the time, the wind is trapped on the left side of his body (somewhere under his ribs beneath the armpit). So I learned to concentrate on that area when burping. It's still the case at 8 months old.
When his body became a bit stronger, I would wriggle his upper body a bit (gently). Sometimes the burp would get wriggled out.
Also my milk is overly"forceful" and goes too fast. That didn't help when he was young as he gulped in too much air trying to keep up. I then learned to feed him when he's lying on top of me so the gravity could help slow down the flow.
Don't know others, but for DS2, it's still a long way before we come out from the gasy influence. At 8 months old, he couldn't nap on his back as the wind would wake him up within 10 minutes. So he naps on me in the day. At night, usually he could cope a few hours in his cot. But by after midnight, the gas we!t through to his butt and coming out as big farts which hurt him into awakening. So usually the second half of the night he sleeps on me, as I'm too sleepy to deal with the frequent wakeups.
