re: Ever had a naturally violent kid?

My 4 yo old daughter has been a terror since she could walk and talk. Been kicked out of 2 daycares. Gets irrationally violent and throwing things when angry and says the meanest things possible. We have tried every sort of parenting you can think of from spanking, time out, taking away rewards, etc etc. you name it we’ve tried it. We’ve heard everything from sensory overload to possibly on the spectrum to she’ll grow out of it. Tried counseling. All of it. Problem is she is way smarter than everyone else her age and just doesn’t know how to put it all together. We did put her in BJJ and she loves it and is taking boys down like it’s nothing. I won’t say it’s a cure but it has helped to some degree by instilling some discipline from someone other than us her parents as well as letting her be rough. We’ve never done medications as we’re both against it but I’d be lying if I said there aren’t days where we are ready to throw in the towel. Keep your head up.
