I noticed with all three of my LOs that if I fed any sooner than about 2 1/2 - 3 hours, they would get a lot more gas. Sometimes feeding more encourages them to get the foremilk, which is rich is lactic acid and can cause a lot of gas. Plus they get in a snacking cycle where they only take a bit of the foremilk, which is not as filling, and don't get to the hindmilk, which is full of the fats they need and that help keep them full. Of course, try to read your own baby, but feeding more frequently never helped any of us. During growth spurts I would do, for example, left side, then right side, then left side again to encourage more milk.
