Children are not simply "little adults". Children's health involves the medical care of infants, children, and adolescents.
The smaller body of an infant is substantially different physiologically from that of an adult. The clinician must take into account the immature physiology of the infant or child when considering symptoms, prescribing medications, and diagnosing illnesses.
It is a natural instinct for parents to panic when they realise that their child has a fever. However, sometimes a fever is good for your child as it is the body's attempt to better combat the bugs at a higher temperature. Nevertheless, children who are less than 3 months old with a fever should definitely be taken to the doctor or if their temperature is above 40 degree celcius.
Routine vaccinations should begin when a baby is 8 weeks old. If it is administered before the recommended age, the natural immunity may hinder the vaccine from working to its full potential. While no vaccine can guarantee 100% effectiveness, it still provides a very good defense against many diseases.
For babies that are born prematurely, it is still imperative that they are given vaccines when they are 8 weeks old as they are more susceptible to infections.
Children should usually be breastfed exclusively for 6 months, and then gradually introduced to whole food into their diet, while continuing to breastfeed for 2 years or so. Avoid feeding children fatty food, ice cream, spicy food or sweetened cereals.
