For a young child, keep it short and playful; for an older child, a bit more specificity goes a long way. Below, a few angles to work from.
For a Young Child
Simple, playful, and often really written with the parents in mind too.
- Happy birthday! Hope your day is full of cake and fun.
- Happy birthday to a truly special kid!
- Wishing you the happiest birthday ever!
For an Older Child or Preteen
A little more specificity works well as kids get older and can appreciate it.
- Happy birthday! Watching you grow up has been so much fun.
- Happy birthday! Hope this year brings you everything you're excited about.
- Happy birthday! You've grown so much this year — can't wait to see what's next.
Short & Simple
For a card or quick note.
- Happy birthday!
- Wishing you a wonderful day.
- Happy birthday — hope it's full of fun!
Frequently Asked Questions

Is a birthday card for a child really meant for the parents too?
Often, yes — many parents read and keep the card, so a warm note works on both levels even when addressed to the child.
