Picky eating behaviour is young children causes parents and carers an immense amount of stress. In most children, the behaviour gradually disappears from school age onwards with no lasting ill effects. There is, however, a small group of children for whom the behaviour becomes 'ingrained' and lasts beyond this age. We'd like to look at these children in comparison with children who don't have this longer-lasting picky eating behaviour to look at the effects on their eating habits during later primary school years. We'd also like to find out how parents' worry about their child's eating as a toddler affects the child's eating behaviour at school age in these children.
