At almost 4 months old, you definitely want that morning A time to be a little longer - hopefully then you can get a longer nap and the day on track. If he's waking at 7am, I wouldn't put him down before 8:30, preferably 8:45. Extend the A time gradually, when he starts acting tired have you tried changing activities and doing something low key like going for a walk, sitting outside, etc? If you can get that first nap to be at least an hour, the second nap would then be 1.75-2 hours after end of first nap, and so on... Have you also read the FAQ section on this board?
