The happy family have all my congratulations and well wishes. As for some advice for the little guy, I'll leave that to Kurt Vonnegut:
Hello, baby. Welcome to Earth. It's hot in the summer and cold in the winter. It's round and wet and crowded. At the outside, baby, you've got about a hundred years here. There's only one rule that I know of, baby—God damn it, you've got to be kind.
