All you can do is involve him in age appropriate situations, such as the pre-school. It will be particularly helpful if he is involved in recreational groups as well. Play groups with a couple or few peers would be good. It's OK to identify with his father, but not to the exclusion of age-typical pursuits.
To be more elaborate, i started him in pre school the second week of school his teacher asked to speak to me, she said he does'nt take part in none of the kids acitvities, he has no lunch, he does'nt use the tiolet and he cries an irritating type of cry all the time without tears to come home. My husband has his own business and he use to take him to work sometimes, so he started saying he's going to work so he can't go to shcool. He's 3 and is most practical he likes to take tools and says he fixing the car, we're do some renovations and he wants, to paint, drills holes in the wall, he drives his power wheel like a big man driving a car. His teacher indicated that we're taking away his childhood. The real problem i guess is how to stop that irritating crying he does.
If you'll offer a bit more information I might be able to guide you. I do not understand what you mean when you say that 'all he wants to do is follow the things his father does'. How is that a problem in your opinion?
