Ds has been very fussy over food for a while. He has been doing his exams and is nearly finished. He doesn’t want breakfast anymore, seems to have a fairly decent lunch but then becomes very fussy at dinner time. He says he feels nauseous sometimes and doesn’t feel hungry/gets full easily. I don’t know what to do. I wonder if it is partly because he goes bed so late and this messes up his rhythm and is overtired, is deficient in something or maybe more stressed than usual due to exams. Has anyone else had this before? I’m hoping to make him write a food diary to see exactly what he is eating. Do I go to the doctor with this? I know he can eat well if he wants but this is very rare
