She is already funny with food (some Sen) and so limited to what meals she will eat.
She is 15. My parents give her £20 a week for lunch and spends. She is using this to buy her own foods for lunch but she would have enough for hot meals . There is also plenty in the fridge she can take .
The problem is she isn't taking it or if I make sure she does it comes back home again.
So yesterday she refused breakfast, had a Pot Noodle 
she bought for lunch if she actually ate it. She came home and was late so went to Cadets straight away. I offered spag Bol and cottage pie for dinner but she chose a pizza but then only ate a small slice.
Obviously I can't force feed her but this has been a common theme for the last three weeks and I am starting to get a bit worried.
