Baby Health

It's worrying when your baby becomes sick. Knowing the symptoms of common baby illnesses is useful when making decisions for your baby’s well-being. Here's some advice about what to expect and how to keep your baby healthy in the first 12 months.

First Year

You may have concerns about your baby’s health during the first year. There are many common health conditions which can occur. A fever is always a concern in infants 0-3 months. Infants less than 3 months old with a rectal temperature of 38° C or higher, or an armpit temperature of 37.5° C or higher should be seen by a doctor. Learn more about common health conditions that may occur in your baby’s first year.

Dental Care

Good nutrition during pregnancy increases the chances for your baby to have good dental health. This continues after birth, when you should continue to build good dental health habits. Keeping your gums and teeth healthy reduces the risk of transferring tooth decay bacteria to your child.  


Your baby will begin teething around 6 months of age. In this section, learn more about common teething concerns and products.

Developmental Problems

If you suspect that your child is showing signs of social, physical or psychological developmental problems, speak to your healthcare professional. 


If your baby cries excessively, he or she may have colic. Although colic can be scary and frustrating for parents, it is considered normal - and temporary.  Learn more:

Respiratory Illness

Your newborn will cough and sneeze to clear their nose and lungs, but this doesn’t mean they have a cold. Don’t give your baby cough or cold medicine unless recommended by your health care provider. A persistent cough, or a cough associated with a fever, or laboured breathing in an infant less than 3 months should always be assessed by a doctor to rule out infection. If your baby is over 3 months of age and has a cough that lasts longer than 3 weeks, or develops a fever or breathing difficulties, you should visit your doctor.
