Why does my kitten follow me everywhere?

I have grown up with cats, and I just got a kitten. I have had him for about 4 weeks and he is 12 weeks old. Great cat…
The only usual thing is that he follows me everywhere, up-stairs, downstairs, in the bathroom, porch, just everywhere around the house. I have never had a cat that did this. Oh and I love that he does it! just curious that he does. Do you think he will grow out of it? or something else?
