ADVICE

TLDR: looking for advice/opinions/experiences with dealing with difficult neighborhood kids/friends of your child. Bullying/lying/stirring up drama. Specifically one kid causing 90% of the issues. My daughter is 4 and plays with a few other kids in the neighborhood, siblings cousins of each other and some not related. My daughter is 4 only child and absolutely loves having friends to play with especially since her first 3 yrs of life were lacking a lot of that connection due to my personal health issues and doing all the parenting alone as well as a couple moves/away from support system. But now im healthier and we live somewhere with more kids! Which is amazing. We're having some serious issues with one kid in particular and after a major issue that happened tonight (I can share more details in pm if asked) I am at my absolute wits end. I know the parents of the other kids and found out tonight they have major major issues with this same kid and they also do not know the parent. They went as far as to say they "HATE" this kid. And tbh I feel the same way atm but I'm trying to tell myself I'm just really upset. I grew up poor and had a lot of abuse in my house hold so i always try to be that neighborhood mom that shares our food/snacks, keeps and eye on the kids and watches their backs even tho they aren't mine. I want them to know they have a safe place and that I won't judge them for acting out or having feelings and just that they have a grown up in their corner just in case maybe their home life is like mine was growing up or even if their homelife is great an extra support person never helped. But this kid. Is really giving me a run for my money. Anyways please help if you have any insight or experience with a kid that isn't yours but you or your child is in contact with a lot that is difficult and how you handled it.
