Hi
DS (6) has taken to saying he is thick. 
He seems to interpret needing to ask for help in class as a sign depsite the fact he tells me others ask for help too. We tried to talk to him about this, focus on the 'trying' aspect and praise where appropriate.
His teacher says she has no worries about his development.
I wondered if there are books for him/we can read together anyone would recommend?
I want to gently convey the message that we are all different and find some things easier than others and that is ok. Trying is the most important thing.
TIA
