Father's Day is a special occasion to celebrate the amazing dads – by birth or by choice – whose lives touch our own. When it comes to your brother-in-law, the dynamic can be extra special.

Finding the right words to acknowledge his role as a dad can be a thoughtful way to show him he's an important role model in your life. Let's find that perfect Father's Day sentiment!

Celebrating Your “Bonus Brother”:

If you're lucky enough to have a truly wonderful brother-in-law, shout it from the rooftops (or at least share how much you appreciate him)! These messages are perfect if you enjoy a close, sibling-like bond:

Father's Day


1. "You're not only an amazing dad and a fantastic brother-in-law. You're also one of the best friends a person could ask for. Happy Father's Day! I'm so lucky to have you in our family.

2. "Watching you be such a great father to my nieces/nephews makes me respect and love you even more. Happy Father's Day to a truly special person, an amazing dad, and my favourite brother-in-law."

3. "Happy Father's Day to the best brother-in-law, coolest dad, and most supportive friend in the world. We're so lucky to have you as part of our family."

Acknowledge the Effort: It Takes a Great Dad:

Dads don't get enough credit for their patience, humour, and the millions of little sacrifices they make each day. Whether your brother-in-law is a seasoned dad or adjusting to a new dad life, let him know that his unwavering love and hard work make a difference.

4. "Anyone can be a birth father, but it takes a kind of man like you to be a truly great dad. Thank you for everything you do, and happy Father's Day!"

5. "You wear many hats – awesome husband, wonderful father, my favourite brother-in-law. You rock them all! Happy Father's Day! We see you, and we appreciate you."

6. "Happy Father's Day to a great dad! You may not always be a perfect father, but nobody loves those kids more than you, and that's the most important thing.

New Dad Nerves? Offer Support & Encouragement:

Becoming a dad for the first time is an exhilarating, exhausting, and life-changing experience. If your brother-in-law is embracing his new dad role, send reassurance and a virtual high-five with these supportive messages:

7. "Happy first Father's Day! The adventure has just begun, and you're going to be incredible. We're so proud of you!"

8. "Welcome to the best (and sometimes craziest) club out there – fatherhood! Wishing you all the best this Father's Day! Here's to an amazing journey."

9. "Happy Father's Day! I'm so excited (and maybe a little relieved!) to watch you grow into the great dad I know you'll be. If you need anything, anything at all, we're here with open arms.

Sincerely Yours:

Maybe your relationship is a bit more formal, or perhaps your brother-in-law simply appreciates the classics. These sweet and sincere messages resonate without being too overly sentimental:

10. "Happy Father's Day! Wishing you a great day filled with all your favorite things, and lots of love from the family."

11. "To the father of our nieces/nephews: Happy Father's Day! Sending you lots of love and warm wishes."

12. "Dear brother-in-law, warmest wishes for a very happy Father's Day! Wishing you all the best."

Laughter: The Best Medicine for Every Dad

If your brother-in-law has a great sense of humour, tickle his funny bone with a lighthearted Father's Day wish! After all, dads need to let off steam sometimes.

13. "Nobody tells dad jokes quite like you! Happy Father's Day to the funniest dad (and brother-in-law!) around!"

14. "I hope your Father's Day is full of well-deserved naps, zero diaper duty, and unlimited snacks. Happy Father's Day! Now go relax a little."

15. "Happy Father's Day! Thanks for always setting such a great example for the kids – especially when it comes to finding the best hiding spots and pulling super sneaky pranks. "

Cards, Calls, Social Media – How to Deliver Your Message:

Deciding how to deliver your Father's Day wishes can be just as important as the words themselves. Here's a quick guide to help you decide what might be the best approach:

  • Card Pros: Great for sentimental types, dads with young kids, or if you want to add a personal touch with a handwritten message.
  • Card Cons: Might feel too formal if you have a super casual relationship, or less environmentally friendly than other options.
  • Calls/Texts: Perfect for a quick heartfelt message, some funny banter, or even to send a silly meme.
  • Social Media: Proceed with caution! Use this if he loves public posts and has a sense of humour. Focus on fun rather than sappy sentiments.

Father Figures & Bonus Dads:

Not all dads are biological, but their love and guidance are priceless. If your brother-in-law has stepped up as a father figure or bonus dad, acknowledge their impact and let them know it matters.

  • "Thank you for being such an amazing father to [child's name]. He/she is so lucky to have you. Happy Father's Day!"
  • "Happy Father's Day to a wonderful brother-in-law! Thank you for being a positive role model and such a big part of the kids' lives."

Wrapping it Up: Celebrating Dads of All Kinds:

Whether your brother-in-law is your best buddy, a new dad finding his way, or an incredible bonus dad – taking the time to celebrate him this Father's Day is a meaningful gesture. It's more than just finding those perfect words, it's about showing your appreciation for the dedication, laughter, and unconditional love that dads bring to our families.

Sometimes, the best expression of love isn't in a fancy gift or elaborate celebration. Offering a helping hand, listening without judgment, or even sharing some goofy dad jokes can mean the world. Fathers come in all shapes and sizes. It's not about having the 'perfect dad' from a storybook; it's about having a person who shows up, cares unconditionally, and tries their best each day.

So, if you have a brother-in-law who has earned the title of 'dad', let him know how much his efforts mean. Share your favourite quotes, a funny Father's Day card, or simply a sincere "You're doing a great job." It's a small way to make a big difference on his special day.
