Breastfeeding question

I wasn’t successful breastfeeding with my first son. . I’ve been exclusively breastfeeding my two month old , but for the past week and a half I’ve noticed that he’s not lasting the 3-4 hours he’s wanting to eat every 2 hours or so, I’m feeding on demand. He’s gaining weight and has well over enough wet diapers . . Am I not producing enough anymore , is this normal ? Or should I be worried .
