What can I do if my child is having trouble sleeping?

Sleep is crucial for a child's development. If your child is having trouble sleeping, establishing a consistent bedtime routine is very important. This includes a calming wind-down period, a set bedtime, and ensuring their sleep environment is comfortable, dark, and quiet. Limiting screen time before bed can also help. Dr. Mitchell can discuss age-appropriate sleep needs, common sleep problems, and strategies to address them. Sometimes, underlying issues like anxiety or medical conditions can affect sleep, which Dr. Mitchell can help assess.

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

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. Mitchell'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.

If my child is referred to a pediatric subspecialist, how can I prepare for the appointment?

If Dr. Mitchell or your family doctor refers your child to a subspecialist, it's helpful to prepare for the appointment. Bring any relevant medical records, test results, a list of current medications, and your child's health card. Write down your questions and concerns beforehand. Be prepared to discuss your child's symptoms, medical history, and any family history that might be relevant. Understanding the reason for the referral and what you hope to gain from the visit can make the consultation more effective.

What are the current screen time recommendations for children, and how can Dr. Mitchell help?

Current guidelines generally recommend no screen time for children under 18-24 months (except for video-chatting with family), and limiting high-quality programming to about 1 hour per day for children aged 2-5 years, co-viewed with a parent. For older children and teens, it's important to balance screen time with other healthy activities like physical activity, social interaction, and sleep. Dr. Mitchell can discuss these recommendations, help your family create a media use plan, and address concerns about the impact of screen time on your child's health and development.
