The day you were born, I got a new title and a whole new kind of love. You changed my world just by arriving.

From the moment I held you, I knew I'd be your number one fan. That hasn't changed one bit.

Watching you grow up is one of the great joys of my life. I hope this birthday is as special as you are.

You'll always have a place at my table, a seat in my car and a spot in my heart. Have a beautiful birthday.

I love the way you see the world: curious, a little stubborn and always kind. Never lose that.

Being related to you is luck. Getting to watch you become who you are is a gift.

No matter how old you get, I'll always be here to cheer the loudest. Happy birthday, sweet niece.

You make our family brighter and our holidays louder, in the best way. Have the happiest birthday.

Happy birthday, little one! I hope your cake has extra sprinkles and your day has extra giggles.

You're five today, which means you're officially big enough for a very big birthday hug from me.

Today you get to be the boss of the party hats. Use your power wisely. Love you!

I love your laugh, your dance moves and the way you tell stories. Have the best birthday ever!

Another year bigger, another year braver. Let's celebrate with ice cream next time I visit.

Every time you draw me a picture, it goes straight on my fridge. Happy birthday to my favorite artist.

I heard there's a birthday girl in the house who deserves the biggest slice of cake. I think that's you.

You make every visit an adventure. I can't wait for our next one. Happy birthday, sweetheart.

Happy birthday to a niece who is figuring out who she is and doing a great job of it.

Sixteen looks good on you. Please drive carefully, mostly for the sake of my nerves.

You're old enough now that I can say this without it being weird: you're genuinely one of my favorite people.

High school is a lot. If you ever need someone who isn't your parent to talk to, I'm a phone call away.

I promise not to post your baby pictures today. Tomorrow, no promises. Happy birthday!

You have a good head, a good heart and great taste in music. That combination will take you far.

I know you're busy being a teenager, but I hope you take a minute today to know how loved you are.

Try new things this year, even the ones that make you nervous. You're braver than you think.

I blinked and the girl who used to hide in my closet became a woman I admire. Happy birthday.

It's been one of my favorite surprises to turn from your aunt into your friend. Here's to many more birthdays together.

You've built a life you can be proud of, and I am. Have a wonderful birthday, love.

I hope this year brings you work you love, people who get you and plenty of time for both.

You're officially old enough to pick the restaurant when we go out. Choose wisely. Happy birthday!

Whatever you're chasing this year, go after it with that same fire you've had since you were small.

Even now, when you call me just to talk, it makes my whole day. Thanks for still wanting your old aunt around.

Being your aunt is the best title I've ever had. Happy birthday from your biggest fan.

An aunt gets the fun parts of parenting and none of the curfews. I've loved every bit of it. Happy birthday.

Your aunt here, reporting for birthday duty: cake, gifts and embarrassing hugs are all on schedule.

I'll always be your safe place, your secret keeper and your shopping buddy. Happy birthday, sweet girl.

If you ever wonder whether someone is proud of you, the answer is yes. Love, Auntie.

Your mom got a daughter, and I got the best niece in the world. I think I won. Happy birthday.

Happy birthday from the aunt who will always pick up the phone, no matter what time it is.

Your favorite uncle checking in. Yes, I'm counting myself as the favorite. Happy birthday, kiddo.

I'm not great with words, but here's the short version: I'm proud of you, and I always will be.

Happy birthday from the uncle who taught you how to throw a curveball and how to sneak extra dessert.

You're growing up smart, funny and tough. Can't ask for more than that. Have a great day, niece.

No matter where life takes you, your uncle is always just a call away. Happy birthday.

I'd write more, but your aunt says my handwriting is a public safety issue. Happy birthday, love you.

Watching you grow up has been one of the best parts of being an uncle. Here's to your best year yet.

Happy birthday to my niece, who is clearly the best-looking, smartest member of the family. Takes after me, obviously.

I was going to get you something really cool, but then I remembered I'm the cool gift. You're welcome.

Your parents raised you, but I like to think I handled the sense of humor department.

It's your birthday, so you get to choose the movie. I reserve the right to fall asleep during it.

Congratulations on another year of being my favorite niece. The competition is fierce, but you keep winning.

Don't tell your cousins, but you're the reason I keep showing up to family dinners.

I've watched you grow from a tiny human who couldn't hold a spoon to a person who out-texts me. Impressive.

Happy birthday to my favorite niece! Have the best day.

Proud to be your aunt. Have an awesome birthday!

Happy birthday, kiddo. Your uncle loves you.

Sending birthday hugs and a big slice of cake your way!

Hope your birthday is as fun as you are, niece!

Love you more than cake. And I really love cake.

Birthday girl alert! Celebrate big today.

Thinking of you on your birthday and smiling. Love you!

I thank God for the day you came into our family. May He guide you and keep you close this year.

Praying that your new year is full of courage, good friends and the quiet assurance that you are loved.

God knew exactly what our family needed when He sent you. Happy birthday, and blessings always.

A niece is a wish that came true, a laugh, a hug, a sky of blue; so on your day I send my cheer and love to last you all the year.

Some nieces are sweet, some nieces are wild, some stay forever a little bit child; mine is all three, and I'm happy to say she's having a really great birthday today.

You were tiny once, I still recall, you barely reached the kitchen wall; now look at you, so tall and bright, your future shining like a light.

Happy sixteenth birthday, sweetheart. I've been thinking about how to put this, so here goes. Sixteen is a big year. You'll get more freedom, more responsibility and probably a few more opinions from adults than you'd like, mine included. So here's my one piece of advice, and then I'll stop: trust the part of you that knows when something feels wrong, and trust the part of you that knows when something feels right, even if it's scary. You have good instincts. You always have. I love you, I'm proud of you, and I'm still available for late-night pizza runs.

Eighteen. I keep writing the number and not quite believing it. I remember your first steps across my living room, your first lost tooth, your first broken heart and how fiercely you got through it. Now you're stepping into a world that's bigger than anything you've known, and I couldn't be more excited for you. Make mistakes, the good kind you learn from. Call your mom. Call me too. And remember that no matter how far you go, there's an aunt back home who thinks you hung the moon. Happy birthday, my girl.

Happy 21st, kiddo. I know everyone's going to tell you to celebrate responsibly, so consider that box checked. What I really want to say is this: watching you turn into the woman you are has been one of the best parts of my life. You're thoughtful, you're hilarious and you stand up for people who need it. Those things matter more than any grade or job title. I hope this next decade brings you good adventures, good friends and a few quiet mornings to enjoy it all. Love you always, Uncle Mike.

My dear niece, every year on your birthday I go back to the day you were born. I was in the hospital waiting room with a vending-machine coffee, pacing like I was the one about to become a parent. When I finally got to hold you, you grabbed my finger and wouldn't let go. You probably don't remember it, but I've never forgotten. Since then you've grown into someone kind, funny and fierce, and I still feel that same grip every time you need me. Have a wonderful birthday. I'm always here.
