7 Pediatrician-Approved Ways to Support Your Child’s Physical Development
By Dr. Katie | Pediatrician + Co-Founder of BIGTIME
As a pediatrician—and sports mom—I always remind parents that supporting physical development doesn’t require expensive equipment, elite training programs, or getting every meal perfectly balanced.
The truth is, most of growth happens through the small habits kids repeat every single day.
This stage of childhood brings rapid growth, increasing independence, changing nutritional needs, and for many families—sports schedules, packed afternoons, and life on the go.
Here are 7 simple ways to help support strong, healthy development during these important years.
1. Prioritize Daily Movement (Not Just Organized Sports)
Physical activity supports muscle development, coordination, endurance, bone health, and confidence.
And movement doesn’t have to mean competitive sports.
Encourage kids to:
⚽ Play outside
🏀 Shoot hoops
🚲 Ride bikes
🏈 Practice skills
🏃 Run, jump, climb, and explore
School-aged children and teens should aim for at least 60 minutes of physical activity most days—but remember, it all adds up.
2. Focus on Nutrition That Builds a Strong Foundation
Growing bodies need fuel.
A balanced plate with protein, fiber, healthy fats, fruits, vegetables, and calcium-rich foods helps support energy, growth, recovery, and overall wellness.
But as parents know—real life isn’t perfect.
Some days look like home-cooked meals.
Other days look like:
• Sports tournaments
• Pizza after practice
• Eating in the car
• Busy school weeks
• Kids who suddenly decide they don’t like anything green
That’s where creating a consistent foundation matters.
For some families, a daily multivitamin can help support nutritional intake alongside a balanced diet.
That’s one of the reasons we created BIGTIME—a pediatrician-formulated multivitamin designed specifically for active kids and youth athletes ages 6–15, with nutrients that support growth and wellness including Vitamin D, Magnesium, Vitamin K2, Zinc, Lutein, and prebiotic fiber.
3. Protect Sleep Like You Protect Practice Time
Sleep is one of the most underrated tools for growth.
During sleep, kids support:
✔ Muscle recovery
✔ Healthy growth patterns
✔ Energy regulation
✔ Focus and learning
General sleep goals:
• Ages 6–12 → 9–12 hours
• Ages 13–15 → 8–10 hours
Try to keep bedtimes relatively consistent—even during busy sports seasons.
4. Build Strength Through Everyday Life
Kids don’t need formal workouts to become stronger.
Simple activities count:
🏊 Swimming
🛝 Playground time
🧺 Carrying groceries
🧹 Household chores
🚶 Walking the dog
🎾 Recreational sports
Strength develops naturally through regular movement.
5. Limit Long Periods of Sitting
Today’s kids spend more time sitting than ever—between school, homework, gaming, and screens.
Encourage movement breaks every 30–60 minutes:
• Stretch
• Walk around
• Toss a ball
• Do jumping jacks
• Practice a skill
Small movement breaks can make a big difference.
6. Move Together as a Family
Kids notice what we do.
Family movement helps make activity feel normal—not like another item on the to-do list.
Ideas:
🚲 Family bike rides
🏀 Evening basketball
🚶 Post-dinner walks
⚽ Backyard games
💃 Kitchen dance parties
Consistency matters more than intensity.
7. Celebrate Progress—Not Performance
Physical development isn’t linear.
Some kids grow earlier.
Some develop coordination later.
Some love sports.
Some don’t.
The goal isn’t creating elite athletes.
The goal is helping kids build healthy habits, confidence, resilience, and a positive relationship with movement.
Celebrate effort.
Celebrate showing up.
Celebrate growth.
Final Thoughts
Supporting physical development during ages 6–15 doesn’t have to be complicated.
Focus on:
✓ Daily movement
✓ Balanced nutrition
✓ Quality sleep
✓ Recovery
✓ Encouragement and consistency
Small habits repeated over time often make the biggest impact.
And remember—perfection isn’t the goal. Raising healthy, confident kids is.
