Birthday Messages for a Niece Who Will Always Be Your Little Girl
No matter how tall she gets or how grown-up her world seems, part of you will always see the little girl who once reached for your hand. These messages remind her that, in your heart, that love never changes.

Sometimes you do not need to overthink it. Just say what you feel.

A little humor works here. Keeps it real.
4. Life moves fast. But some things stay the same. Like the fact that you will always be my girl, no matter how many birthdays go by. I hope today is full of happiness and love.
