124+ Birthday Wishes for Your Younger Sister That Will Touch Her Heart

As young as you were
And as old as you’ll be
Just remember that you’ll
Always be older than me!

Happy birthday from your
Beautiful younger sister!
Happy birthday to my young mom!

People often mistake us for sisters,
and who could blame them!

You’re so young-spirited and youthful-
looking that of course people would
never think you’re my mom at first glance!

I too love having a mom who is more like
a sister, as I can talk to you about anything
and everything!

Enjoy your special day! Love you, mom!
You might be older than me, but I’ll always look out and care for you as if you were my younger sister!

Happy birthday to you today!
We might not see each other as often as we used to when we were younger, dear sister, but I hope you know that you’re still just as important to me and you’ll always have a special place in my heart.

Wishing you the best birthday, sis.
My amazing elder sister, today we’re celebrating another wonderful year of your life! Happy birthday!

Ever since we were young, I have looked up to you and turned to you for guidance. You have, and always will be, such an inspirational person to me.
Happy birthday, cousin!

You might not know this, but I’ve always
seen you as more of a younger sister
than a cousin.

It doesn’t even have anything to do with
age, it's simply the fact that you’re just
as annoying as a little sister!
How is it possible that you can be younger than me, yet at the same time look so much older! I guess it’s just the result of having all that wisdom and maturity!

I’m wishing you a fabulous birthday this year, my dear little sister!
Happy birthday to my wonderful sister!

Elder siblings don’t always get along with their younger brothers and sisters, however, you must be the exception with me, sis!

You’ve nurtured me and always had time for me; you’re the best elder sis I could’ve ever hoped for!
Happy birthday to my dear sister who I’m actually quite fond of now!

She’s not nearly as bad as I used to think she was when we were younger!
Happy birthday to my fantabulous sister!

You might have some growing up to do
yet, but there’s still plenty of time to get
to that at some point, sis!

Just enjoy life while you’re still young!
Well youngish, at least!
Happy birthday big brother from your visibly younger, funnier, and more attractive sister!

Don’t worry, you also have some good attributes too - they're just perhaps a little less obvious!
Having a younger sibling like me is tough competition and while you may not have won the title of favorite child when we were growing up, you’ll always hold the prestigious position of fav sister to me!

Happy birthday to you!
Wow, another birthday already…
I know that you’re my big sister and all,
but you don’t have to make it so obvious!

I’m just kidding with you, of course!
You still look super young, sis!

I’m wishing you a wonderful birthday today.
When you close your eyes and blow out
the candles on your birthday cake today,
sis, I know you’ll be wishing for one thing
and one thing only: to be younger!

How do I know this? Because it’s what
we all wish for, of course!

Happy birthday, my dear sister!
Happy birthday to my favorite little guy!

I’m lucky that you’re my brother, but you’re even luckier to have an elder sister like me who loves and appreciates you so much!
