So I am having some issues with my 4 year old step son. It seems as though his terrible two have gone on to the 3's and into the 4's, and grown with severity. There is not a single thing that I have found/tried that works. I tried the nice gentle approach, to which his reaction is to laugh and trample all over me. I've tried the stern voice thing, yeah, again nothing. I've done the spanking (let the judgement begin), but nothing seems to work on this kiddo. Does any one have any suggestions on how to deal with a completley defiant, very aggressive 4 year old boy?
