My DS 3 has always been picky with food (and needed a lot of persuasion to learn to sit and eat by himself). He has recently started nursery. Today at pick up we were told that he refused to sit and eat his lunch and asked to sort it out. What do we do? He is usually ok at home. Sometimes he will get up a lot etc but he will normally sit and feed himself. How do we make him eat when he is a thing nursery?
