Baby Journey helps you understand why your baby is fussy — not just track that they are. Our unique “Why difficult today?” feature decodes crying and clinginess into leaps, growth spurts, teething, or tiredness, with reassuring tips for each. A traffic-light timeline shows upcoming developmental leaps before they hit. Plus: a Parent Stress Tracker, age-matched play ideas, pregnancy-to-birth continuity, and multi-baby profiles for twins or siblings. No data collected, no data shared.
