Gimages you should get proper instruction from a guy who knows how to throw one. We stayed away from the one that requires a tomahawk wrist action which I refer to as a ML CB. That one we learned at 15 yo.
In all cases at a Young age the coach calls the pitches and often they still think CBs are harmful. The CB my son used as a 10yo was a slip Curve where the fingers were involved more than the wrist. It created a beautiful smooth delivery and no sudden shock to the elbow. He varied the grip slightly to vary the break movement. He also used a modified CU with a late break. The batters didn't know what was coming and he mixed in an occasional FB. I looked for a video of him pitching but nothing at a young age . The youngest was at 16 against some college and ex pros in the intercounty league here.
I do think you should get pro help.
