Does anybody have a good behaviour/reward/punishment system for their 2.5 year old? Mine has become so defiant, I went and bought a "toy jail" box. He gets a warning, a countdown from 5 and then loses a toy and if he carries on he continues to lose toys. He isn't so fussed yet but I've realised this is quite one sided in terms of negative/punishment so wondering what I could do to balance with positives/rewards (that aren't food or new toys)
