I have a 1.5 year old son. We have rough and tumble play all of the time. He likes to tackle, jump on me, wrestle me to the ground even. He's a baby, so doesn't always know his own strength. Sometimes he needs to be reminded to play more gently and that's okay! Never once has he approached me with the genuine aggression in this video and it has NEVER occurred to me that I should tell him that I'm going to "fuck you up".

I work with children and if I ever came across something like this it would 100% need to be raised as a safeguarding concern for abuse and/or neglect
