One idea, in the UK, it was a tradition to buy a cask of vintage port at the birth of a child. Port is a fortified wine, so it will age much longer than dry wines. Also, vintage port needs to age for some time. This year is likely to be a vintage year, but you won't be able to buy 2003 for some time. You could buy an earlier, but more recent vintage. Just make sure you buy "vintage" port as opposed to ruby, tawny or late bottle vintage port.
