Ds is 23 months. He is already in the system, due to having 2 older sisters with ASD, and having absolutely no words at all at 18 months.
On Wednesday I had to leave dd2's school play , as he was giving a (loud 
) running commentary on what was happening, and dd2's arrival on stage got him wildly excited.
Today, we popped into town to grab something from the shops. Job done, we returned to the car. As I strapped him into his seat, he protested "hot, hot! Mummy car, hot!" I chatted back, saying I didn't think it was too hot, etc etc (usual toddler flannel, averting meltdown etc)
Ds paused, looked at me, considered a bit, and said 'warm' with total finality.
Made me lots. Don't think there's much wrong with either his language comprehension or production!
