What will my son be like in 3 years what will I be doing in the future

I can't be certain, but you'll likely be very involved in his life.
You will probably get him into social situations so he'll learn to interact with others his age.
Later, introduce him to Scouting. Scouts was a blast for me!
Then perhaps sports of some sort. He will hopefully develop interests of his own, as well.
Maybe take him camping or to the Smithsonian...
It's a big world. There's lots to be doing in the future.
Go with him. Grow with him. Never forget to tell him that you love him.
