The big one!!!

I don't know what to do. I am so tired of the fighting. I try to just talk to him. I try to reason with him. If I tell him no or to choose something else he cries or whines that I am not fair. Today we went tobogganing' he cried all the way up but guess what he loved it and did it again. We have tryed counseling and it works for awhile but I don't have the money to keep going. I talk to him ask him whats going on how he is feeling. I am trying to my best to be as good as mom as I can but man this is hard. We have laughs lots of laughs but sadly also lots of tears from both of us. Sometimes I just feel like a failure.
