DS aged 5 kept telling me for weeks nobody played with him, he had no friends, he was sad and upset. After about 6 weeks of this I approached the class teacher, and just said gently "DS keeps saying nobody plays with him/he has no friends, I just want to check if this is true, because well you know kids"....
She smiled and said "DS is the most popular child in school, what a story teller, even the older children like to play with him in the yard, he has plenty of play options don't worry"
I blushed on the spot and said I'm so sorry to have asked.
DS came home that day and pleaded again he had no friends I turned round and said "funny you should say that because Miss X said you had loads of friends"
His eyes widened, he looked at the floor. I just said AHH yes mummy talks to the teachers, so shall we try that again.
He's never lied about school since and he's 7 now 😂
