Jackie is 5 and has not been at school long. She has coeliac disease so her mother provides her with a suitable snack for break and a packed lunch. The school has its own cafeteria and the food on offer is particularly exciting to the children. The sweets and cakes also appeal to Jackie despite her being warned that she must not eat anything other than what is in her lunch box. Her little friends have been taught to share and this they do regularly. They don’t think it is fair if Jackie is told she is not allowed one of their biscuits. On a few occasions the teacher has noticed Jackie running to the toilet frequently after lunch.
