I agree with the other posters, he is starting down the long road of domination and unless you check him now he will be a danger to you and your children. I once had a rooster that almost took my eye out, they can be vicious, unpredictable creatures and learning how to deal with them from day one is imperative to having a happy flock.
You must learn right now that he is not your pet, nor is he your friend. He serves one purpose, to fertilize the hens eggs and offer some protection to the flock. When you walk out into the coop/run walk with purpose, walk tword him with confident strides and force him to remove himself from your path. if he just merely moves out of the way and watches you, keep at him until he moves and keeps moving. If he does the side step dance twords you make him stop.. Part of me thinks it may already be to late and hopefully others will chime in with more suggestions.
For future reference... Never hand feed or "cuddle" your cockerels.
