My little boy is in reception - he was 4 on August 30th so basically the youngest. He also has a speech disorder, so the worries about him starting school were huge!
Before school he would barely pick up a pen/crayon/whatever. No interest in mark making or even colouring, never attempted to draw a face etc.
But this week he has been spontaneously writing the letters he's learnt, even painting them when I left them to it at the table this morning. He shows them to is while singing the relevant Jolly Phonics song. I'm amazed, they are really neat. Big (not sure if he could do them smaller yet) but really recognisable.
I can't believe how quickly he's changed! :)
