Child Developmental Milestone Tracking Skill
Child developmental milestone tracking and assessment based on ASQ-3 and Denver II standards, providing early warning for developmental delays.
Core Flow
User Input → Parse Operation Type → Read Child Information → Calculate Age → Determine Assessment Items → Generate Assessment Report → Save Data
Step 1: Parse User Input
Operation Type Mapping
| Input | action | domain |
|---|
| record | record | all(default)/gross/fine/language/social/cognitive |
| check | check | - |
| milestone | milestone | Optional: specify domain |
| delay | delay | - |
| history | history | - |
Developmental Domain Mapping
| Input Keywords | domain |
|---|
| gross motor | gross |
| fine motor | fine |
| language | language |
| social | social |
| cognitive | cognitive |
Step 2: Check Information Completeness
Required (prompt to set if missing):
- Child name (from data/profile.json)
- Birth date (from data/profile.json)
- Gender (from data/profile.json)
- Prematurity status (from data/profile.json)
Prompt when child profile missing:
Child profile not found
Please set child basic information first:
/profile child-name Xiaoming
/profile child-birth-date 2020-01-01
/profile child-gender male
Step 3: Calculate Age and Months
birthDate = profile.child_birth_date
today = new Date()
ageMonths = (today - birthDate) / (30.44 * 24 * 60 * 60 * 1000)
if gestational_age < 37 && ageMonths <= 24:
correctedAgeMonths = ageMonths - (40 - gestational_age) * 4
else:
correctedAgeMonths = ageMonths
Step 4: Generate Assessment Questions
Determine Key Milestones by Age
6-Month Assessment Example:
Please assess whether milestones are achieved (yes/no):
Gross Motor (6 months)
Can sit briefly without support
Can support self on hands during tummy time
Can roll from back to tummy
Fine Motor (6 months)
Can reach for objects
Can transfer items between hands
Can pinch with thumb and finger
Language (6 months)
Can make single syllable sounds (ma/ba etc.)
Responds to sounds
Can turn toward sound source
Social (6 months)
Shows stranger anxiety
Laughs out loud
Can express happiness/anger
Cognitive (6 months)
Looks for dropped objects
Can distinguish familiar/stranger faces
Step 5: Generate Assessment Report
Developmental Assessment Grading
| Assessment Result | Condition |
|---|
| Normal | All domains meet age standards |
| Possible delay | 1-2 months behind |
| Significant delay | 3+ months behind |
Normal Assessment Report Example:
Developmental Assessment - Normal
Assessment Information:
Child: Xiaoming
Age: 6 months
Corrected age: 6 months
Assessment date: July 1, 2025
Gross Motor Development:
Sitting alone: Achieved (at 5 months)
Rolling over: Achieved (at 4 months)
Tummy time support: Achieved
Assessment: Normal
Fine Motor:
Reaching for objects: Achieved
Transferring between hands: Achieved
Pincer grasp: Not achieved (normal, ~9 months)
Assessment: Normal
Comprehensive Assessment:
Normal development
All developmental domains within normal range, no significant delays detected.
Recommendations:
Continue observation and recording
Provide rich environmental stimulation
Interact and communicate with child frequently
Regular developmental assessments
Step 6: Save Data
Save to data/child-development-tracker.json, including:
- child_profile: Child basic information
- developmental_tracking.assessments: Assessment records
- milestone_achievement: Milestone achievement statistics
- alerts: Developmental warnings
- statistics: Statistical information
Key Milestones by Age
0-3 Months (Early Infancy)
| Age | Gross Motor | Fine Motor | Language | Social |
|---|
| 1 month | Lift head briefly | Eyes follow | Cooing | Gaze at faces |
| 2 months | Lift head 45° during tummy time | Hands together | Laugh | Social smile |
| 3 months | Lift head 90° during tummy time | Grab rattle | Smile at face | Smile at face |
4-6 Months (Mid Infancy)
| Age | Gross Motor | Fine Motor | Language | Social |
|---|
| 4 months | Head steady, roll | Reach for objects | Squeal | Laugh aloud |
| 5 months | Sit with support | Pincer grasp | Turn to sound | Recognize strangers |
| 6 months | Sit briefly | Transfer objects | Single syllables | Stranger anxiety |
Developmental Delay Standards
| Domain | Mild Delay | Significant Delay | Severe Delay |
|---|
| Gross motor | 1-2 months behind | 3-4 months behind | >4 months behind |
| Fine motor | 1-2 months behind | 3-4 months behind | >4 months behind |
| Language | 1-2 months behind | 3-4 months behind | >4 months behind |
| Social/Cognitive | 1-2 months behind | 3-4 months behind | >4 months behind |

Medical Safety Principles
Safety Boundaries
- No developmental disability diagnosis
- No future developmental level prediction
- No substitute for professional developmental assessment
- No intervention training program recommendations
System Can
- Developmental milestone tracking
- Developmental delay screening
- Early warning alerts
- Assessment history records
Important Notice
This system is for developmental milestone recording and reference only, cannot replace professional medical diagnosis.
Development has individual variations; being 1-2 months behind may be normal variation.
If significant developmental delay is found or you have concerns about development, please consult a child health specialist or developmental behavioral pediatrician promptly.
