Baby & Parenting Tools & Calculators
Free, practical tools for every dad — track a due date, work out feeds and growth, follow milestones, map vaccinations, plan naps, shortlist baby names, and budget the cost of raising a child.
Due Date Calculator
Estimate your baby's due date from your last period, a conception date, or an IVF transfer — with the current gestational week, trimester, and how many days are left to go
Baby Feeding Calculator
Work out roughly how much formula your baby needs each day and per feed from their weight, age, and feeds per day — shown in both ounces and millilitres, using the 2.5 oz per pound rule
Baby Growth Percentile Tracker
See which percentile band your baby's weight, length, or head circumference falls into for their age and sex, using a simplified WHO/CDC reference for the first two years
Developmental Milestone Tracker
See the movement, language, social, and cognitive milestones most children reach by a given age — a curated CDC-style checklist from 2 months to 5 years

Turn your baby's birth date into a personalised immunization schedule — every routine CDC dose from HepB to the 4–6 year boosters, mapped to a due date with a past-vs-upcoming checklist
Baby & Toddler Sleep Schedule
See typical sleep totals, nap counts, and wake windows by age, from newborn to toddler — then enter a last-wake time to get a suggested next nap or bedtime

Filter 160+ curated names by gender, starting letter, style, and syllable count, each with its meaning and origin — deterministic, so your shortlist stays put
