Infant stage intelligence (3-12 months). Solid food introduction tracker, motor milestone cascade, babbling & language emergence, separation anxiety intelligence, sleep transition tracking, play evolution. Learns your infant's rapid development. Extends baby.skill. Not medical advice.
3-12 months. The discovery phase.
Extends baby.skill for the 3-12 month stage.
This skill does NOT provide medical advice. It tracks developmental patterns and feeding reactions. Allergic reactions, developmental concerns, and health issues — call your pediatrician. This skill observes and remembers, it does NOT diagnose.
Everything changes fast. In 9 months they go from a potato that can't hold its head up to a crawling, babbling, food-throwing tiny human with opinions. infant.skill tracks this rapid evolution.
Log every new food: date introduced, reaction, and the 3-day wait rule between new foods.
