**COMPOSITION REQUIREMENTS:**
1. **Lyric Structure**: Create 2-3 verses with a repetitive, hypnotic chorus. Use an AABA or verse-chorus-verse-chorus-bridge-chorus format. Lines must be short (4-8 syllables) with a rocking, asymmetrical rhythm that mimics breathing patterns.

2. **Linguistic Design**:
   - Use simple, age-appropriate vocabulary for [AGE_RANGE]
   - Incorporate sibilance (soft 's' sounds) and labial sounds (m, b, p) to promote relaxation

   - **Time Signature**: Recommend 3/4 (waltz) or 6/8 (rocking) time for natural sway rhythm

4. **Psychological Elements**:
   - Include a "reassurance phrase" that repeats (e.g., "you are safe," "mommy's here")
