Different Types of Allergies in Babies and Toddlers

There may be instances when you see that your baby's skin has rashes, and it does not feel so soft. Alternatively, your baby sneezes or sniffles every once in a while. These are some of the symptoms of allergies in babies.

This article throws light on the causes, symptoms and prevention of various allergies in toddlers and infants.

Allergies in babies are just as common as allergies in adults and grown-up children. Infants and toddlers have allergic reactions in their bodies when they eat certain foods or touch or inhale unseen particles. Allergic reaction to medication or food normally happens just after they consume them.

The types of allergies in babies are -

• Food Allergies: Food allergies are one of the most common allergies in a baby. About six million babies and toddlers have an allergic reaction to certain foods. This is more common in boys than in girls. Food allergies in kids can cause life-threatening conditions like extreme breathing trouble, anaphylaxis and sudden drop in blood pressure.
• Seasonal Allergies: In this case, allergy symptoms in babies become worse in seasons. The common seasonal allergies cause sniffling, sneezing and wheezing when some grasses, trees and weeds bloom.
• Indoor Allergies: The dust particles and mites can also cause allergic reactions to your little ones. One in every six kids has a type of indoor allergy.
• Pet Allergies: Your fluffy dog can cause allergic symptoms to your baby. Cats cause pet allergies the most. However, dogs can also be the cause of allergies. In such a case, keep a pet that will not cause an allergy, like a fish
