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


Happy birthday to one of my dearest relatives! You might only be my cousin but to me, you will always be much more like an annoying younger sister!
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!
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!
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!
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!
I’m wishing the happiest of birthdays
to you today, my dear sister.

The special connection that we share is
something I simply couldn’t live without.
You’re the sweetest, kindest, and most
supportive sister I could ever wish for,
and I’m so grateful to have you in my life.

I truly am very blessed to be your
younger brother.
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!
While you might be getting older, sis,
you can always look at me to remind
you what young looks like!

I’m just kidding with you! You look
really good considering your age!

Happy birthday to you from your
hilarious and beautiful younger sister!
Happy birthday, sis! On your special day, I want you to know that no matter how old we get, the fact will always remain that you are my younger sister and I’ll always be there to look out for you.

You’re my little sis and I care about you and love you a lot! I hope you have a fabulous birthday today!
There’s no one else like
My sweet eldest brother
You’re funny and unique
Simply unlike any other!

Happy birthday from your 
Younger sister who loves 
You lots and lots!
Happy birthday, my dear sister!

Don’t feel bad because I’ll always
be younger than you; if anything
you should feel bad that you’ll
always be older than me!

I’m sending you all my love and
best wishes to help you celebrate
your special day today.
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.
Happy birthday, sis!

When we were younger, there were definitely times where I couldn’t stand to be around you. Nowadays, I can’t stand being away from you!
