I would highly doubt that it's genetic.
But just like your own self-harm did, it probably serves him some purpose... to get held by mommy? to pull mommy away from what she's doing? to test his own ability to get himself un-stuck? to chase that invisible squirrel that no one else can see?
I don't have any suggestions for making it stop, but looking into potentional reasons for why it's happening in the first place might give you a place to start.
Then again, it might be one of those many random "doesn't have much to do with anything" crazy things that toddlers do!
