Childcare MET Value: Official Values for Every Childcare Activity
Official MET values for childcare activities from the Ainsworth Compendium. Casual play is MET 3.0, active games MET 3.5, running games MET 5.0. Full table and calorie calculation guide.
Childcare activities have MET (Metabolic Equivalent of Task) values ranging from 1.5 to 5.0+ depending on the specific activity. The official values come from the Ainsworth Compendium of Physical Activities — the standard scientific reference used by researchers and health organizations to classify exercise intensity.
Use the Playing with Kids Calorie Calculator to calculate calories burned for your specific weight, duration, and play type.
What Is a MET Value?
MET stands for Metabolic Equivalent of Task. It describes how much energy an activity requires relative to sitting quietly at rest.
- MET 1.0 = sitting quietly (your resting metabolic rate)
- MET 2.0 = activity burns twice as much energy as sitting
- MET 3.5 = activity burns 3.5× more energy than sitting
- MET 6.0 = vigorous exercise (e.g., cycling, aerobics)
A MET value of 3.0 means the activity burns 3 times more energy than sitting. This is the threshold commonly used to define "moderate physical activity" by health guidelines.

Detailed Breakdown: Play Activity MET Values
The three play categories used in this calculator correspond to these official Compendium values:
| Calculator Category | Compendium Activity | MET |
|---|---|---|
| Casual Play | Playing with children, light effort | 3.0 |
| Active Games | Playing with children, moderate effort | 3.5 |
| Running & Chasing Games | Playing with children, vigorous effort | 5.0 |
What counts as each level?
Casual Play (MET 3.0): Activities where the parent is mostly seated or stationary — board games, arts and crafts, storytelling, building with blocks, reading aloud. Movement is incidental, not sustained.
Active Games (MET 3.5): Activities requiring sustained standing and moderate movement — playground supervision with direct participation, throwing and catching a ball, hide-and-seek, moderate outdoor games where the parent is actively involved.
Running & Chasing Games (MET 5.0): High-energy activities involving sustained running — tag, relay races, chasing games, active backyard play with sprinting. The parent is continuously physically active, not just supervising.
How to Calculate Childcare Calories Using MET
The MET calorie formula is:
Calories = MET × Weight (kg) × Time (hours)
Example 1: 70 kg parent, 30 minutes casual play (MET 3.0)
Calories = 3.0 × 70 × (30 ÷ 60)
Calories = 3.0 × 70 × 0.5
Calories = 105 kcal
Example 2: 75 kg parent, 45 minutes active games (MET 3.5)
Calories = 3.5 × 75 × (45 ÷ 60)
Calories = 3.5 × 75 × 0.75
Calories = 197 kcal
Example 3: 80 kg parent, 60 minutes running games (MET 5.0)
Calories = 5.0 × 80 × (60 ÷ 60)
Calories = 5.0 × 80 × 1.0
Calories = 400 kcal

Why MET Values Vary in Practice
The Compendium's MET values are population averages. Your actual calorie burn can vary by ±15–25% because:
Individual fitness level: Less fit parents use more energy for the same movement patterns because their bodies are less efficient. Conversely, highly trained parents may burn slightly less than the MET value suggests.
Actual vs. labeled activity: 30 minutes of "active games" may include 5–10 minutes of setup, hydration breaks, or managing disputes — reducing actual active time.
Terrain and environment: Outdoor play on varied terrain (hills, uneven surfaces) burns more calories than the same activity on flat indoor surfaces.
Child's demands: A highly energetic toddler who requires constant chasing demands more from a parent than a calmer child who plays more independently.
Temperature: Playing in cold or hot conditions increases calorie burn slightly as the body works to maintain core temperature.
Is Childcare a Significant Source of Physical Activity?
For many parents, childcare represents their primary source of daily physical activity. Research supports this:
- Parents of young children (under 5) accumulate significantly more steps per day than the general adult population when actively engaged in childcare
- Active childcare (MET ≥ 3.0) qualifies as moderate physical activity under WHO and CDC guidelines
- Parents who replace passive supervision (watching from a bench) with active participation can double or triple their childcare-related calorie burn
Practical implication: For parents who struggle to find time for formal exercise, maximizing the physical intensity of childcare — choosing running games over passive observation, carrying rather than stroller-pushing where safe, and doing active playground activities rather than sitting — can meaningfully contribute to daily physical activity targets.
Frequently Asked Questions
What is the MET value for playing with children?
The Ainsworth Compendium lists three MET values for playing with children: 3.0 (light), 3.5 (moderate), and 5.0 (vigorous). These correspond to casual play, active games, and running/chasing games respectively.
Is childcare considered physical activity?
Yes. Activities with MET ≥ 3.0 qualify as moderate physical activity, which includes most active forms of childcare (playing at the playground, carrying toddlers, running games). Passive childcare (watching children play, reading to children) falls below this threshold.
What is the MET value for carrying a baby or toddler?
Carrying a young child while walking has a MET value of 3.5 — equivalent to brisk walking. This makes it a genuinely useful calorie-burning activity throughout the day.
