Though many children may never have allergies and those that do might have such mild reactions that they are missed completely and disappear, some children are more susceptible than others. Allergies in children can affect varied age groups in different ways. Younger children and infants might get eczema or develop asthma during their early years. Some will grow out of these and some will go from one allergy to another, known in the medical world as a progressive allergy disease or atopic march. Generally most childhood allergies manifest themselves in about ten to twenty percent of kids, usually seen in their early infancy as eczema, itchy rashes that develop on the cheeks, scalp, legs, arms and in creases all over the body.
Milk allergies are usually related to cow’s milk, though usually any childhood milk allergies are gone by age three. However, sometimes these can last a lifetime and begin in early childhood. In fact, the allergic reaction to milk usually happens within minutes or might not occur for up to four hours, lasting up to a full day. More severe reactions can result in a shock reaction which requires emergency care. Regardless of the reaction time, a milk allergy does not necessarily have to be as a result of drinking milk as it can come from any type of milk product or food. In some cases, the reaction does not occur until there has been a substantial build up over time of the milk proteins. It can happen through varied forms, including drinking and eating, but also skin contact with a milk product, something that has been in contact with a milk product or someone who has had a milk product and still has remnants on their skin or lips.
