Super super fast eater?

Ch
Hi guys. Newb here. My little guy is 3 months and weighs around 18.5 lb. (born 10lb) He's always been a pretty quick eater, but he's down to only 3 minutes on one side and he's happy for 2.5-3 hours. I've tried bringing him back to the breast for more but he cries when I do. I do have an strong letdown and great supply, but I am worrying about how he can possibly get enough in 3 minutes. Anyone else's baby super speedy?
