My 2&1/2 year old girl is overactive ,naughty,hard to control,tantrums?

When shes naughty or out of control just give her a spanking not like your beating her but a little spanking on the butt will show her that thats not okay. And if she crys that's okay there's supposed to be some pain to show her it's not okay. And know that your doing this out of love so she doesn't grow up to be a brat and remind her that mommy loves her or daddy loves her. Hope this helps. :)
