A brief guide to 12 most common childhood illnesses

Food-allergiesIt is quite normal for any child to suffer from food allergies especially if there is a family history of asthma, eczema, hay fever or lactose intolerance. To check the allergic nature of your child, it is recommended to introduce solid food mainly iron rich foods at 6 months while continuing with breast feeding.

It is not wise to leave out foods like milk, eggs, wheat and nuts just because they are labeled as allergy causing foods. Your child may or may not be allergic to all these food items. Sometimes introducing allergy causing foods before completing 1 year of age may reduce the risk of developing allergy with that specific food.
