Schedule?

My boyfriend said I should get our son on a nap schedule. I just don't know how. He's 2 months old, I've stayed home since he was born but I'm going back to school in two weeks so he'll be at my bfs moms. (Why he says that cause she watches his nieces to). He eats on demand(formula). He just doesn't sleep in the day hardly. Sometimes he'll fall asleep in my arms for like a half hour at most, and he takes about one good nap in his swing. I try to lay him down other times in his swing but he just stays awake. I just kind of let him nap when I know he's getting tired. But again a lot of it he'll fall asleep in my arms and as soon as I lay him down he wakes up. Unless he's really tired, but it doesn't happen a lot. So what should I do and how do I do it?
