75 First Birthday Wishes for Your Son

Here's the thing about a first birthday card: he can't read it, and he won't remember the day.
So write it for the person who will read it — the fifteen-year-old who finds a box of old cards one afternoon. That's a completely different card from "Happy 1st Birthday, little man!", and it's the one worth writing.
Seventy-five wishes below, from short card lines to the longer messages worth keeping.

The one thing worth doing
Write the date on it, and put it somewhere safe. A card is a card; a card with a date and a few honest lines about who he was that year becomes the thing he keeps.

Frequently asked questions
He can't read it, so write it for the version of him who will — at fifteen, going through a box of old cards. That framing changes what you write: less 'happy birthday little man', more what he was actually like this year and what you hope for him.
