If you really want to bond with your son, canning your criticism isn't going to be enough. You've got to exhibit a positive attitude when you're around your son. Like everybody else in this world, he just wants to feel loved, and sometimes the best way to show him how much you care is to simply tell him. Even if you're the kind of guy who doesn't like to express his feelings, you can still let him know how proud you are of him. Point to something he's done recently and tell him that he did a good job, or just make an effort to say something positive to him every day. Of course, a simple "I love you" will also always do the trick.
