SENCO and class teacher said "It's not bad parenting. There's no such thing as bad parenting."
I feel so supported by them. I could cry with relief.
Then they said it sounded I needed extra suport dealing with DS2s challenging behaviour - and would I like to come in and talk to them every week?
Bet you all wish you had my fantastic SENCO 
(They said all this despite saying that they don't see any challenging behaviour at school - which I think they don't. He's a little angel at school
)
