after 3 weeks at school eating sandwiches my daughter got a bad cough/cold and went off food. ever since i have day after day where she has only eaten a quarter of a sandwich all day. I have asked the teacher for help and she has watched and said that dd isn't talking all dinner time or doing anything unusual. It's now got to the point where it's taking over an hour to eat a few bites of food and everything i have tried isn't working. she won't even eat her most favourite foods. please can someone help me
