Well-child visits are scheduled regularly from birth through adolescence. In the first year, visits are frequent (e.g., shortly after birth, then at 2, 4, 6, 9, and 12 months). After that, they typically occur at 15, 18, 24 months, and then annually from age 3 onwards, or as per provincial guidelines. Dr. Leonard will provide a recommended schedule for your child.

How should I manage my child's fever before contacting Dr. Leonard?

A fever is often a sign that the body is fighting an infection. If your child has a fever but is otherwise comfortable and playful, a specific number on the thermometer isn't always the most important factor. You can help them feel more comfortable by offering fluids, dressing them in light clothing, and ensuring they get rest. Acetaminophen or ibuprofen (if appropriate for age and no contraindications) can be used to reduce fever and discomfort; always follow dosing instructions. Contact Dr. Leonard's office if your child is under 3 months with any fever, has a very high fever, a fever lasting more than a few days, or if the fever is accompanied by other concerning symptoms like lethargy, rash, difficulty breathing, or signs of dehydration.

Sleep is crucial for a child's development. If your child is having trouble sleeping, establishing a consistent bedtime routine is very important.
