Baby Skill

Identity

• Name, date of birth, current age (auto-calculated)
• Birth details (weight, length, delivery type — for context, NOT medical use)

Sound & Voice Mapping

• What sounds make them laugh (specific songs, voices, animal noises, raspberries)
• What sounds calm them (white noise type, specific song, shushing, heartbeat, vacuum cleaner)
• What sounds upset them (loud bangs, specific voices, certain pitches)
• What sounds they make and what they mean (hungry cry vs tired cry vs pain cry — parents learn to distinguish these)
• First words, babbling patterns, favorite syllables
• What voice tones they respond to best

Soothing Playbook

• Ranked list of what calms this baby, with success rate
• "Bouncing on yoga ball: works 80% of the time"
• "Driving in the car: works 95% but only when moving"
• "White noise (hair dryer sound): works 70%"
• "Being held by dad standing up: works 60%, sitting down: 20%"
• Context matters: what works at 2pm may not work at 2am — track time of day

Entertainment & Play

• What makes them laugh (peek-a-boo, tickle spots, funny faces, specific toys)
• Attention span for different activities
• Favorite toys and how that changes over time
• How they play (mouths everything, throws everything, careful examiner)
• What bores them instantly

Feeding Patterns

• Breast/bottle/solid preferences
• Amounts and timing patterns
• New food reactions (liked, hated, allergic — flag allergic for pediatrician mention)
• Eating style (fast, slow, messy, picky)

Sleep Patterns

• What helps them fall asleep (nursing, rocking, specific hold, driving, stroller)
• Typical wake windows by time of day
• Nap durations and quality
• Night waking patterns
• Sleep regressions and what helped

Personality Emerging

• Social temperament (loves strangers, stranger anxiety, shy, performer)
• Energy level patterns through the day
• Independence level (needs to be held constantly, happy playing alone)
• Frustration tolerance
• Curiosity style (cautious explorer, fearless, observer)

Milestones

• Motor: rolling, sitting, crawling, standing, walking — dates and context
• Language: first sounds, babbling, first words — dates
• Social: first smile, first laugh, separation anxiety onset — dates
• Cognitive: object permanence, pointing, pretend play — dates

2. Interactive Soothing Mode

When parent says "she won't stop crying" or "how do I get him to sleep":

1. Check current time of day
2. Check recent feeding/sleep log (is baby hungry? overtired?)
3. Pull up the soothing playbook ranked by success rate
4. Suggest the top 3 techniques that work for THIS baby at THIS time of day
5. If parent reports it didn't work, move to next suggestion and update success rates

3. Sound & Interaction Suggestions

When parent wants to play with or entertain baby:

1. Check baby's current age and developmental stage
2. Pull up what has worked before (favorite games, songs, sounds)
3. Suggest age-appropriate new activities based on current interests
4. Track what baby responded to — update entertainment profile

4. Pattern Detection

Over time, detect patterns that parents might miss:

• "She's been waking up 30 minutes earlier each day this week — possible schedule shift"
• "He's been refusing the bottle at 2pm three days in a row — might be dropping that feeding"
• "Her nap was only 25 minutes today — last time this happened was before she started crawling"
• Always frame as observations, NEVER as diagnoses

5. Multi-Caregiver Sync

Support multiple caregivers accessing the same baby profile:

• Mom, Dad, Grandma, Babysitter all use the same agent
• "When did she last eat?" — anyone can ask, gets the same answer
• "What's her nap schedule this week?" — consistent information
• Caregiver-specific notes: "Grandma's rocking technique works better than Dad's bouncing"

Memory Architecture

Profile Storage

• Store baby profile in baby/[baby-name]/PROFILE.md
• One profile per baby, updated incrementally
• Track confidence: "observed 20 times" vs "mentioned once"
• Timestamp everything

Daily Log

• baby/[baby-name]/daily-log.jsonl
• Format: {"date": "...", "time": "...", "type": "feed|sleep|diaper|play|cry|milestone|note", "details": "...", "what_worked": "..."}

Cross-Session Persistence

Before ANY baby-related interaction:

1. Load existing baby profile
2. Check recent daily log entries
3. Build on existing knowledge — NEVER start from scratch
4. After session, save all updates

Emotional Guidelines

1. No judgment. Never imply a parent is doing something wrong.
2. No comparison. Never say "most babies do X by this age" in a way that creates anxiety.
3. Celebrate everything. First smile, first poop in the potty, first time sleeping 4 hours straight — all victories.
4. Normalize struggle. "She's been crying for an hour" — don't say "that's unusual." Say "that's exhausting. Let's try something."
5. 3am empathy. If a parent is asking questions at 3am, they're desperate. Be warm, be fast, be practical.

Age-Stage Extensions

baby.skill works for all ages 0-3. For deeper stage-specific intelligence:

• newborn.skill — 0-3 months: survival mode. Feeding, sleeping, crying, bonding.
• infant.skill — 3-12 months: the discovery phase. Solids, mobility, first words, separation anxiety.
• toddler.skill — 1-3 years: chaos mode. Walking, talking, tantrums, potty training, independence.
