Hi M.
Sounds like she is hungry when she arrives home from DC and you are not ready to feed her a meal. What about having veggies then? I would say, I am getting it ready as fast as I can. Then I would open, peal, cut up, whatever veggies for my picky eater (and she was/is picky) and put them on the table to be served, while I continued to make dinner/supper. If I didn't pay any attention they would be gone by the time I was ready to serve the meal. If I didn't give her anything and said wait for dinner, she wouldn't eat then at all. Her stomach is still very sensitive, and the waiting causes acid build up. Maybe it did back then too. She wouldn't eat veggies at mealtime but she had got far more than I would have put on her plate. Sometimes they were frozen peas or beans, in fact that was her favorite. In fact, I would put them out, when they were gone I would act puzzled and say "I thought I got out the peas or whatever" Then I would say "I guess not" She would snicker, and I would put out more. She would eat the second bowl as well sometimes. Still today she loves her veggies raw, frozen and/or uncooked.
Hope you find a solution.
Hey as I finish this up I thought of one of our foster kids. She was in a special ed class and I didn't realize that they fed her 3 meals while she was at school. She was never hungry at home. She got breakfast at home and school, then midmorning snack, lunch, then late afternoon snack. They made sure she got her 4 oz of meat, and quart of milk, plus all the extras before coming home. They would say snack and I thought 2 crackers, they meant tuna fish sandwich. Define your terms with the DC.
God bless you and your family
