Today I tried to make a dad joke for the first time, and no one got it

I am a fairly quiet, reserved individual. I was hanging out today with a bunch of friends and family at a ball game, mostly with some other dads that I hang out with.. sometimes, and quite enjoy doing. However, I still usually keep quiet and fill in the ad-libs in the conversation. I don't make the jokes or tell the stories.

I took my kid and their cousin for a walk around the park we were at to just have them chill in the cart for a little bit, and so everyone else could watch the game. As I was leaving, the other dad said to his kid, something like "he has free reign on you, you better be good."

They were both great honestly, but halfway through, the cousin gets a small nosebleed, which happens from time to time, its common, I know that. So when I was getting back I told everyone the kid had a small nosebleed, and looked at the kids dad (and one other dad in the group), and said "You said I had free reign on the kid right?"

Now, I don't know if he actually thought I hit his kid, if he completely forgot what he said and was just confused, if he thought I meant that the kid was bad on the walk, or if the joke just wasn't that funny, but by his face, a dad joke was the last thing on his mind.

I still don't even know if he knows.
