DS1 as you all know is as / hfa with severely challenging behaviours
He has always been able to eat a wide range (a blessing) but latelt has been shrinking that down
He's not exactly fat (curly haired one on my profile) to put it mildly but he has lost almost a stone and is doing things such as binning food thinking we don't know, weighing himself obsessively (scales ditched today.
I had eating disorders as a youg woman but ds1 is only 9.
Help!
