Personally I am grateful if you check your bag as it leaves more overhead space when I travel economy cabin. But Don't ask me to check mine.
Let the child decide for themself, but start with a bag that conforms to IATA guidelines.
And you're misguided about overhead space, as those that check bags will still have a cabin bag for the overhead locker.
