Tools & capabilities
Baby Age tools 5

Use for any 'how old is the baby' question instead of computing it yourself.get_milestone_datesGet the exact calendar date of all 25 baby milestones for a given birth date (monthly, special days, and birthdays), each with days_left and whether it is reached. Use this to add baby milestones to a calendar.list_milestonesList the 25 baby milestone types this tool knows (name, emoji, day offset from birth, group). No birth date needed. Use get_milestone_dates to turn these into real dates.get_zodiac_signGet the zodiac sign (Western astrology) for a birth date, with element, nickname, date range, and a guide link.get_birthstoneGet the full birthstone guide for a birth date's month: every stone (some months have three) with colors, hardness, sources and story, plus meaning for the baby, keepsake ideas, a safety note, the month's zodiac signs, quick answers, and a guide link.
