I don't have such a habit. My parents were never into similar stuff, neither our extended family nor was it common generally where I grew up. I could start doing it as adult living away from them but decided not to, after seeing how affection for sweet junkfood messes up with women en masse and how utterly weak they are against these cravings. And there are some guys in same boat too.

Same for sodas btw, we generally didn't have them, and later I've never found sparkling-anything appealing, remove the bubbles and drinks become oversweetened sewage. Same for champange/prosecco compared to good white wine for 1/2 the price. Best beer lagers from the bottle I've tasted are those Bavarian treasures that have comparably little co2, which messes up tastes badly. If I anywhere get over-co2 beer I know they don't care about quality, just cheap filler.

My best friend's parents bought a machine that was putting co2 into tap water, never grokked why the heck do they go through all the effort to make something so bad in taste compared to original.

Do your kids a favor, don't make sweet stuff some great thing deserved after hardship. You may extend their lifespan by a decade or two and make them overall stronger humans.
