Birthday Card Messages for Son, From Mom and From Dad

Writing something inside your son’s birthday card always sounds easier than it actually is. You sit there with the pen in your hand, the card already picked out, and somehow nothing on the page feels like it covers it. “Happy birthday” alone feels like it’s missing something.

Whether he’s turning six or twenty-six, what he actually wants to read is something that sounds like you, not a line from the card aisle.

This list covers short messages for when you want it simple, long ones for when you don’t, messages written specifically from a mom’s voice and a dad’s voice, and a few that fit a son who’s already grown up and out on his own.

If you’re writing cards for the rest of the family this season too, these birthday card messages for dad carry the same tone, and the full birthday card messages collection has even more to pull from if none of these feel quite right.
