Wishing your own son a Happy Birthday is pretty darn easy. You’ve known him all your life, you have a strong connection and bond – he’s a member of your closest family. So writing a birthday message or getting him a card isn’t anything you have to worry or stress about.
But saying “Happy Birthday son-in-law” can be a different story altogether. You may not know him as well, what he likes and dislikes, and you may be fearful of causing offence.
Let’s be completely honest: you’re not his mother or father. So there’s always the possibility you over step the mark and say something inappropriate or that he isn’t comfortable with. So something that on the surface seems easy has the potential for problems.
But that’s why we’ve put together this guide on what to write in a birthday card for a son-in-law. You’ll find a great range of birthday wishes and messages for your son-in-law, from sweet and touching to funny and insightful quotes.
You can use them in cards, on social media like Facebook, or even use them to say to your son in law in person.
