I see that your boy naps alot. how long he sleeps in the day? not true that boys are difficult to handle.
I understand your frustration because I had gone with it before. Not knowing what they want and why they cried. My son used to sleep thru up to 10mths and then started to cry in the night.
You have to find ways to understand why he cries..Did you try to feed him? change him etc?
