Am i wrong? (Not pregnancy related just a rant)

Shaylein • Im 25 pregnant with baby number 3! I have 2 boys so im hoping for a girl!! *update* im having a baby girl!!! so excited!
I have a 2 year old he is very busy and hard headed😑 he throws temper tantrums as well lol BUT I always get after him whenever he does something wrong but someone Is always butting in trying to yell at or whoop him and when I tell them to leave my child alone they get mad at me and say "he's going to run over you" or "he's going to Be beating your ass once he's older" now I understand no one likes a bad kid but I feel if I'm disciplining him there's no need for anyone else to discipline him as well or even yell at him it annoys me to the point where I started keeping my kids away from everyone including family and now everybody is mad because my kids don't know them but I do not like for people to hit or yell at my kids! Am I wrong? I don't hit or yell at their kids so why can't I get the same respect? I could see if I wasn't disciplining him but I do🙄🙄
