Any advise on why my baby is not gaining weight?

My baby is EBF and not gaining weight. At birth lo was 8.11 and had no problem getting back to birth weight within a week. (No latch issues whatsoever) Now at 6months lo is 14.4. We feed on demand and I'm fairly certain it's not a supply issue. I pump at night after lo goes to bed and usually get 2oz and feed 3-4 times through the night? I have also tried block feeding to make sure he gets hind milk and it doesn't seem to help. However, he is fairly content and hitting all milestones. Any advice???
Also- he usually has a poopy diaper everyday and multiple wet diapers so I'm so confused why he's not gaining...
