Growing Pains in Kids — Nighttime Leg Aches and the Stretches That Actually Help
Your kid wakes at 2 a.m. crying, grabbing their calves. You rub, they fall back asleep, and it happens again three nights later. This is growing pains — and the fix is simpler than you think.

What growing pains actually are
Growing pains is a misnomer. Bones lengthening doesn't hurt. What's actually happening: muscles and tendons haven't kept pace with rapid bone growth, and during busy play days they accumulate fatigue and tightness. At night, when the body relaxes, those tight muscles spasm. That's the pain.
Prevalence: 10–40% of kids ages 3–12. More common in active kids. Peaks during growth spurts.
Classic symptoms
- Pain in calves, shins, or behind knees — almost always both legs, not one
- Late afternoon, evening, or middle of the night
- Goes away by morning, kid runs around fine the next day
- Responds to gentle massage, warm baths, heat pack
- No limp, no swelling, no redness, no fever
When it's NOT growing pains — see a doctor
- Pain is always in one leg (could be Sever's, Osgood-Schlatter, stress fracture)
- Pain during the day too, especially with limping
- Swelling, redness, warmth
- Fever or fatigue
- Joint pain, not muscle pain
The 5-stretch bedtime routine that fixes it
Do these 5 minutes before bed, every night for 2–3 weeks. Most parents report nighttime pains stop or reduce dramatically within that window.
