Perhaps you received a train set, a doll's house, a construction kit or a board game that kept the whole family entertained.
Those memories can remain remarkably vivid, even decades later.
This Christmas, why not consider giving someone a present that takes them back to their childhood?
Retro toys and games have a special appeal because they combine entertainment with nostalgia.
Traditional wooden toys, model vehicles, spinning tops, puzzles and construction sets are still available, although modern versions sometimes differ from those we remember.
Classic board games are another excellent choice. Scrabble, Monopoly, Cluedo and chess have entertained generations of families.
For adults who remember their childhood Christmases particularly fondly, reproduction toys and vintage-inspired gifts can provide a wonderful surprise.
Music offers another possibility.
A collection of favourite songs from someone's teenage years, perhaps accompanied by a book about the performers, could make a thoughtful present.
Books themselves can also transport us backwards in time. Reprints of childhood favourites, annuals and illustrated stories may bring back memories of Christmas mornings long ago.
Of course, nostalgia isn't confined to toys.
Traditional sweets, old-fashioned decorations and classic Christmas films can all recreate something of the festive atmosphere of earlier decades.
If you're buying an older or collectible toy, check its condition and suitability. Vintage toys may not meet today's safety standards and are often better treated as display pieces.
What makes these gifts special isn't necessarily their monetary value.
It's the memories they unlock.
At That's Christmas 365, we'd love to know which Christmas present from your childhood you remember most fondly.
Was it something expensive and elaborate, or a simple gift that somehow became unforgettable?
