Birthday Wishes for Sister
A sister is the one person who remembers your worst haircut and loves you anyway. These birthday wishes for your sister — elder or younger — go from sweet and emotional to the kind of teasing only a sibling gets away with. Copy one into the family chat, or send her a birthday wish link that opens like a present: her name in fireworks, candles to blow out, your old photos and a letter from you.

Tips for writing birthday wishes for sister
Dig out an old photo
Childhood photos are the sibling superpower. Add two or three with captions — the matching outfits, the bad haircut — and they float by as polaroids in the surprise.
Tease, then mean it
The best sister messages open with a joke and end with one sincere line. Pick a funny wish and add “but really, I don’t know what I’d do without you.”
Elder or younger, say which
An elder sister likes to hear thanks for looking out for you; a younger one likes to hear she turned out brilliant. Change one line to fit.
