Signs of success is when the child begins becoming upset at home (sign things are being tackled) – Known in psychology as the “extinction burst” – worsening of the behaviour before it stops and goes extinct.
Remember: Help guide the child to the answer – don’t give them to her/ him & of course keep practising at home what is learned in session.

Also… Reward coping behaviour through small acts:
– Smiling at him/ her
– Tell him/her what you like about what he’s doing
– Give a pat on the shoulder or back
– engage him/ her in a conversation
– Later in the day, tell him/her that you noticed he was coping so well
