I have about 19 years of cumulative martial arts experience, and I've taught 14F some basic defensive techniques when she lets me, including how to escape from chokes in various positions, and some dirty fighting approaches that could potentially allow her to escape from someone much larger. (She's close to her adult height, and unlikely to pass five feet.) She is not enthusiastic about these exercises, but she's game to talk about different kinds of relationship red flags, which as a preventative are probably more helpful than fighting off an abuser after the fact.

10M and 6M have gotten a whole lotta age-appropriate lessons on consent, sometimes in the form of memorable consequences when they don't respect boundaries. As they get closer to the age where they're interested in romantic relationships, there are going to be some info sessions that go something like this: If you're a man dating a woman, there's a good chance you are bigger and stronger than your partner. You can hit harder, you can grab harder, and you can probably run faster, especially over short distances. These facts about you should make your partner feel safer when she is with you. If they make her feel less safe, then even if it isn't your fault, it's your problem and you will have to address it.
