its really hard to ignore some things so if one of my girls start first thing i do is move them to somewhere they cant hurt themselves ( this has only happed a couple of times with adele touch wood colbys been good so far :lol)
and let her get it out her system, i made the mistake of laughing at her once and she flipped went bananas and tried to bite me

ignoring them does work it just takes a little time till they realise they dont get any attention from it
