But taking a positive spin on things, thats great! Youve come a step closer to understanding his unsettledness. In future, just what i would do, is when he has been awake for a while and is getting grizzly, instead of trying to settle him for sleep, always offer a feed first. A bit like feed, play, offer feed, sleep. If a bub is unable to settle, i think offering a feed is always useful - at least if he is not hungry, sometimes a breastfeed can just provide comfort. And i agree with pp about keeping a diary and writing down feed, sleep, grumpy, settling, etc times - it really helps bring clarity to his needs.
