How do you stop a 3 year old child from misbehaving?

your child is acting like a three year old because he/she is 3...they are curious and want to do things on their own...and they usually won't take no for an answer...but i know what worked for me and that is to compromise...if you won't eat your peas then you get no desert...that doesn't work but maybe if you say eat three peas, b/c that's how old you are, and give an incentive that is visual at the ready then it might work...what ever you do...don't listen to ANYONE who wants to medicate your child, which will be suggested when your child hits kindergarten...say no...tell them to deal with your child's personality...that is all it is, a personality...let it shine...direct his/her energy towards something that your child might enjoy, like swimming, karate, football, Ballet, just a suggestion...i have three kids...two turned out successful, one is a herion addict...he was the one the teachers wanted on Ritalin...biggest mistake i have ever made...if you research, children on Ritalin or aderall or any kind of ADD meds... are most likely to be an addict....don't make the mistake i made...let your child bounce off the walls, take things apart...that is their personality...deal with it...find your own solutions....compromise, make deals...give praise...but punishment is necessary as well...good luck
