When my daughter was born, I wanted to cherish every moment with her, and love her more than a dog loves a human. I did. Do the same, take lots of pictures and videos, record his voice often. Even if you cherish every second like it is the only moment in time that matters, they still grow up too fast. Blink twice and they're adults. Always be here and now, but get those recordings. Not only are they great for nostalgia, but if you get enough records of them saying dumb (but cute) things, you can always use that when discussing things with them and show them how they have progressed in development. If they are going to do something dumb, or say something dumb but are just too young yet to realize why it is wrong, you can show them videos of stuff they said or did when they were younger and ask them how they could have been better. Then get them to apply the same thought process to the present moment and they learn how to figure things out. If you address everything with them when they're young, they won't hide things from you when they're teenagers, but instead will come to you to talk out their problems if they know you won't judge them, and just want them to be happy and get through life's problems. Let them know the mistakes you made in your past and teach them to learn from the mistakes of others so they don't have to make the same mistakes again. As soon as he is old enough (4 or 5 or whatever it is) get him into swimming classes so by the time he is 15.5 or 16, he can get a job as a lifeguard. It pays well and it will keep him fit.
