At his graduation my LO was distressed. No tears by still didn’t join in and very stressed looking. I ended up taking LO off the stage. Held them hoping to get them to join in but we ended up leaving the hall. His key worked brought his certificate out to us later. Obviously we said he’d done brilliantly and not to worry as he kept mentioning lots of people looking and I know he as upset with himself. Since then his behaviour has been awful. Lots of hitting shouting screaming general defiance. Calling out for me at bedtime. Mainly out of character. I know it’s linked back to the stage fright. Just back from few days away where his behaviour was improving towards the end and when we got home he saw his certificate on our fridge and said he didn’t want it up and to put it in the bin. 
So how to we overcome this. I feel it’s really shaken him. He’s due to start school soon and was previously confident and looking forward to it.
