I have a picture on my door from 18 months ago, of a man pushing a baby in a pushchair, and a cat. Ds1 was 3 when he drew it. It's very recognisable.
He is now 4.5, and brought an unrecognisable scribble home from school. His drawings at home now look like the ones he did when he was 2. I haven't said anything to him about it, but I am finding it a bit worrying, TBH. Anyone else's child's drawings regressed? should I mention it to his (already hideously over worked) teacher?
