The footage to gather

  1. The preparations
  2. A favourite interaction
  3. The moment after the candles

Give each moment a little breathing room. Get close enough to show the detail, and keep the original clips handy.

Plan a chronological montage

Opening

Establish who, where and when with one clear opening.

Middle

Choose a small set of meaningful scenes and use plain transitions so time stays easy to follow.

Ending

Return to a moment that connects everyone in the story.

Review it for birthdays

Ask before posting identifiable guests and keep private wishes out of public edits.

Ask yourself: Are the dates and relationships clear to a relative who was not there?

Watch it as if you were seeing it for the first time. If something is unclear, try a different cut or add the missing shot.
