Brian,
He'll grow to appreciate good music, it seems all youngsters have about a 3 second attention span - the important thing is that he is happy and healthy, everything else will fall into place. I have a 18 month old god son who is just a ball of energy, so I pretty familiar with what your going through :)
Life has been interesting, I sold one of my business about 4 months ago, it had been in the works for around 2 years and I am now "retired" and am enjoying every minute of it. I have a few projects going on up here, but plan to move to a warmer climate with in 2 years at which point I may get back to being a serious audiophile, though I must admit I am happier with less - so who knows.
