Some children experience unpleasant reactions after eating certain foods.
They might be sick, have diarrhoea, cough or wheeze or get an itchy rash, but they often outgrow these food sensitivities. However, some foods may cause a reaction so severe that it is life-threatening. Thankfully this affects very few children. The foods most likely to cause a problem for small children and babies are often the ones they first meet at weaning. So it is sensible to avoid giving these foods until a baby is at least six months old.
