Sweetie, children are different based on temperament more than gender. If you want your son to have certain characteristics then try to nurture those characteristics in him. I can't stand any kids (boy or girl) who are dirty, out of control, rough-housing at inappropriate times, or mouthy. I crack down on those behaviors with both of my sons and my daughter equally. I get compliments frequently about how calm and sweet both of my sons are. There is a great chance your son will be everything you want him to be if you nurture him to be those things.
I will apologize in advance for bringing this up, but this post hits a completely raw point for me today. I just saw on Facebook that a very good friend of mine had a tragedy in her family. Her son was also just 5 months old. He was born withsome heart problems and was in the NICU for 6 weeks. However, he had a surgery and during that surgery doctors found that his heart was in much better condition then they could have dreamed. They gave him an excellent prognosis and sent him home with plans for one minor future surgery. He went in for that surgery today, this morning to be exact. His parents handed him over to the doctors expecting to see him again but he died on the operating table. I know it's so hard to see through GD (I had it too so I really do understand), but try to imagine if that was your son. Would it really matter that he was wild or played games you didn't like? There are more important things to worry about than stereotypes for children.
Hang in there sweetie and raise him nurturing those good characteristics and you will have a man you can be proud of.
