Well, I understand the new-parent exuberance, but I'd just say that I think you may lose the energy for that kind of thing over time :) Sure, you can make an email address for a one year old, but it is not going to be useful for an extremely long time, and there is a non-zero chance it will never be useful at all, because email will no longer be a useful thing by the time it would have been. Seems like premature optimization!

But of course there's also nothing wrong with thinking about and doing this kind of stuff even if it never turns out to be very useful, if you enjoy it, that's enough :)
