There is (was) actually a device that replaces the original driver (the bit the cog fits onto and moves the clutch back and forth to drive or brake) with one with a freewheel thread, allowing you to fit a regular freewheel so you can back pedal. However, it's much easier to just dismantle the hub and take the brake shoes out. Just undo the drive side cone nuts, take the driver out (turn it clockwise as you pull to keep the clutch threaded on), then take out the brake shoes and slide the clutch and driver back in. Tighten the cones as normal (no play in the bearings but as loose as possible) and you effectively a freewheel hub you can roll back on without the cranks spinning.

You want an ACS freecoaster, although I don't think they make em anymore. With the turn of two little screws, you can alternate from freewheel and coaster brake. I used to have one...many years ago on my freestyle bike. It was a very cool contraption that works with a standard coaster brake.
they pop up on ebay from time to time...

No coaster braking
I am sorry if I got you all in a mess. I want my kid to be able to counterpedal without braking as in a regular bike. In this way he will be able to put the pedal in a correct horizontal position for him to start pedaling by counterpedaling when stopped in a more intuitive way.
Thanks again
Thanks again
