85 3rd Birthday Captions (Because He Can Tell You He's Three)

Three is the first birthday he participates in. He knows it's coming, he can tell you how old he is, and he has strong feelings about the cake — which means the best captions this year are the ones that quote him.
Eighty-five below, grouped by tone. The short ones are first because they're the ones most people actually need.

What he said
The ones that work best are the ones you write down at the time.
- "I am free." — him, correcting nobody
- "This is my best day."
- "Is the cake for me? All of it?"
- He looked at the balloons and said "wow" very quietly.
- "I'm three now so I can do it myself."
- "Again" — about everything, all day
- "Don't sing." Then: "sing again."
- "That's my cake and that's my chair."
- Asked if he'd be four tomorrow.
- "Best day ever" — declared at 8am, before anything happened
For the party photos

- He wanted balloons. He got balloons.
- Everyone came. He noticed.

Sibling and family

The one thing worth doing
Write down what he actually says today. Not for the caption — for you. The caption is the excuse; the record is the point. In two years you will not remember that he said "I am free," and you will very much want to.

Frequently asked questions
Three is the first birthday he has opinions about, so the best captions quote him. 'He picked the theme himself' or the exact thing he said when he saw the cake beats anything generic. If you want short, 'Three' with the photo doing the work is genuinely enough.
