Using a child account set up in Family Account on FitBit

Is it possible to sync the steps for a child account within a family account on Fitbit?

Sorry I didn’t even know a child account exists. Does it have its own credentials? If it does, then you should be able to sync your Fitbit with the game.

No, they have a username, but I log in and then go in to the child’s account.

Is there a way to do this yet?

So does it work when you try to sync after loading steps to Fitbit app?
