What do y’all do when you feel ur child is being described negatively to people ?

Went to visit some family my cousins has a 4(5 in November ) year old boy as well While he went to work I would hang out with her because we both have kids my LO is 2. Well she likes to comment how my son is aggressive and how he’s like idk how to translate this but like just mean I guess to her son. Which is not true my son is on the good side he’s fucking two to add on top so even if he was bad compared to ur son? You can’t compare a new toddler to a school attending preschooler. I told all of them idgaf if my 2 really hurts ur 5 year old then you need to teach him to speak up more and defend myself because he would cry if my son didn’t get punked out by him. He only does things because we were at their house and their son didn’t want to share nothing! And every toy my son grabbed he would snatch away and my son doesn’t like that so will take it back and I’m like ur sons being a butt people don’t react for no reason Anyways just wanted to post it to get off my chest since I know it’s not a big deal but I don’t want to be around people who see my son as an aggressor or even talk bad about him. Meanwhile my cousin tells me oh no my son was hell at 2 he bite everything and everyone so in my head I’m like bitch 👀😭😂 their kid isn’t bad just a big ass cry baby so that was the stressor this week. Thank god my Lo didn’t pick up the habit. They buy him every toy from every store! That’s not the party that brother because I know kids are gonna ask but it’s the crying 😭😭😭 Like bro he would cry cry cry and then she would complain about my LO throwing a tantrum. Idk u know people don’t like people saying things about their kids so that’s just how im feeling. She tells every on my son is rough with her son again because he takes toys doesn’t share and cry like a fucking 1 year old 😭😭😭😭
