difficult child has been on Adderall XR since October with a now 12 lbs weight lose. We saw a nutritionalist last week who said she thinks we need to see a developmental pediatrician as difficult child may have more going on (sensory issues, developmental delays, etc) than just lose of appetite from the medications. Well, she was eating okay and didn't lose any weight in January, which is good, but starting refusing to eat earlier on this week. Other than a bit or two in the AM and then one thing from her packed lunch (usual the 'junk' item I send), she hasn't eaten much else everyday this week. Tonight she tells me she is hungry but won't eat. When I ask why she just says 'because.' She seems fully aware that not eating could really harm her body and put her in danger of having to go and stay at the hospital but she seems to not care. Does anyone know if this is a sign of an eating disorder? I have already asked her the usual questions... are you afraid of becoming fat, does it hurt when you eat, are you scared to eat, etc but it has gotten me no where.
