Sleep advice? Please!

I'll try to make this brief. The first month of my son's life was easy sleep-wise. When he was tired he just fell asleep, no matter what was going on. We'd lay him in his bassinet and we'd get a good 2 hour nap in each time. Now that he's almost 2 months old I struggle catching when he's tired and one of two things happens. 1) He falls asleep nursing or 2) He becomes over-tired, causing him to cry until he eventually falls asleep nursing (sometimes takes several sessions with almost constant crying between them). I've become his sleep crutch. He'll only fall asleep while nursing. I need help knowing when/how often to put him down for a nap before he becomes too tired. He'll be 2 months old on the 14th. We usually wake up for the day around 6:30-7:30 am and go to bed around 10:30 pm. How long should he be awake between naps? Or how many should he get per day?And how do I tell when he's getting tired? He's also eating about once an hour right now if that helps. I'm in desperate need of some advice. It breaks my heart to hear him cry so hard every day because he's tired...he won't go to sleep no matter what I do. 😢 Please help!
