Too early to say for sure, but artificial sweeteners might be bad for kids.

Their bodies are still calibrating on how sweetness translates to calories.

Diet sodas are very sweet but provide no calories.

So their bodies might take it as a general rule either that very sweet things are safe to consume in excess, or that their expected intake always falls short of their actual intake so they should overeat across the board.

Again, it’s too early to say for sure, but there are enough plausible concerns that I wouldn’t automatically assume it’s fine.
