Some feeds are good but a lot are fussy. Forceful let down, maybe over supply? He feeds on demand but usually 2-3hourly but just tops up. He comes off and on, breaks suction, and always has soooo much wind.
In the night it's lately been 3-4 hourly. But he just won't latch sometimes but will want feeding.
He is bothered by gas a lot but I try all little ways to relieve it. He's gaining so well so that's not the issue, it's trying to make it more enjoyable for us both. My two daughters fed to 15 months, it was very painful with them until 10weeks with the first and three weeks with 2nd but not fussiness like this time around.. 
He's also had thrush for three weeks that were both being treated for.
He's currently just had a fussy feed and is filling his nappy with the second poop in five mins. Along with some monster burps
