Thanks for answering those questions! Based on what you're saying, I think you probably have a high supply, and that is causing fast letdowns and high lactose intake, both of which are contributing to the baby being gassy. Probably. Now, if a mom has bad oversupply and it's causing problems for the baby, the remedy is often block feeding (feeding on just one breast at a time for 1 or more feedings in a row). But block feeding is something you do only if you are 100% certain you have an oversupply, and you're not 100% certain. And you're already nursing on just one breast per feeding, which is the most minor version of block feeding. So I don't think you need to do anything more to manage your milk supply other than continuing to avoid the pump (if possible) and letting nature take her course; oversupply diminishes with time as long as you feed on demand, and babies usually grow into fast letdowns.
It would probably also help to feed in reclined (a.k.a. biological nurturing) positions, because they enlist gravity to slow milk flow and make nursing more comfortable for the baby. Don't be afraid to let your baby nurse for comfort- that is actually a very good thing for a baby who is having trouble with fast letdowns, gas, colic, etc. The breast is designed to provide food and comfort, not just food.
So, aside from fast letdowns and possible oversupply, what is going on with your baby? My guess is that she is just being a baby! Babies are gassy, fussy...
