I wait and count to 4 if there still going at it then i get involed Cheyanne is still correcting Phoenix and she'll snap at him with her teeth showing and it looks like there fighting but 2 seconds after there fine i give her the chance to correct him first then like i said if it last longer then the 4 seconds i get them away from eachother i've only had to do it a couple times though they usally stop before i need to get involed

I also use the same with with the 2 boys Aspen + PHoenix
