Vaccinations, Well-Child Visits, Minor Illness

It’s true that our pediatric care team works to help you keep your child healthy by offering vaccinations and well-child visits. But even with the best intentions, it’s inevitable: sometimes kids get sick. From a common cold to the flu, we’re right here when you need us.

Pediatric Acute Injury and Sports Medicine

It’s bound to happen. A twist of the ankle when running, a skinned knee from a bike fall, or an injured arm or shoulder after a tough baseball game or gymnastics meet. At AdventHealth Ottawa, formerly Ransom Memorial Health, we’ll help you avoid urgent care or the emergency room by treating minor injuries, including sports strains and everyday bumps, bruises and cuts.

Newborn Care

It’s an exciting time when your baby arrives. Let our newborn care team help you get your precious little one on a healthy path, starting with a priority appointment with us within two to three days after birth. We offer a wide range of newborn care services including circumcision, guidance on car seat safety, help with constipation and colic, nutrition services, breastfeeding support and more. And since there’s so much to learn as a new parent, we’ll help you get comfortable with the basics of newborn baby care, including:

  • Bathing
  • Caring for a healing circumcision
  • Cleaning the umbilical cord
  • Dressing
  • Feeding
  • Sleep safety
  • Soothing
  • Swaddling
Chronic Conditions in Children

If your child is diagnosed with a chronic condition, such as asthma, allergies, eczema or something more serious like, stomach issues or diabetes, we’ll help you and your child understand their condition and develop an individualized treatment plan, including tools to help with management and coping strategies.

Camp and Sports Physicals

Annual physicals are important to keep a child’s health on track. And sometimes specific exams are needed for camps, sports or school. We’ve got you covered. At AdventHealth Ottawa, we’ll help get your child ready and make sure they’re healthy and physically prepared to participate in the fun.

Children’s Mental Health Care

If your child or teen is having difficulty with their emotions or behaviors, a mental health evaluation may help identify the underlying cause. We evaluate for and treat many common children’s mental health care concerns, including attention issues, headaches, social conditions, depression and anxiety.

Teen Health and Wellness

It can be tough to be a teen: They face so many physical and emotional changes, pressures and stresses. Today’s teens face health concerns unique to their stage of life, including:

  • Eating disorders
  • Reproductive health issues
  • Sexually transmitted infections
  • Substance abuse challenges 

Sometimes teens feel embarrassed to talk to their doctor about these issues. We get it, and our teen health and wellness specialists will work with your child to help them feel supported. 

Exercise with a Doctor

Helps Kids Stay Active and Healthy

At an early age, it’s important to help kids build the foundation for a healthy lifestyle. That means developing healthy eating and exercise habits that will carry them through life. The team at AdventHealth Ottawa believes that staying active is important for the development of a healthy heart, lungs and mind, and keeps muscles and bones strong. 

Here are a few reasons why it’s important to help kids become and stay active:

  • Active children are more likely to become active adults
  • More physical activity in children is associated with higher test scores in reading and math
  • Regular exercise promotes self-efficacy with regard to health and self-image
