About KidBeast.com
KidBeast.com is an independent, advertising-supported website built around six free calculators for the day-to-day questions of expecting and raising a child, plus a small museum of childhood play. There’s no company behind it beyond the site itself, no staff directory, and no membership tier — just tools built to be genuinely useful, and ads that keep them free.
Before the due date
The Due Date Calculatortakes the first day of your last period and your typical cycle length and works out an estimated due date using Naegele’s rule, along with rough markers for the end of your first and second trimesters. It’s a standard obstetric estimate, not a diagnosis — actual delivery dates vary widely even in low-risk pregnancies, and your midwife or doctor’s own dating (often confirmed by ultrasound) should always take priority over anything a calculator says.
Feeding and sleep, in the thick of it
Two tools cover the stretch of parenting that runs on the least sleep. The Baby Feeding Calculator estimates how much formula a baby needs per day and per feeding from their weight, using the commonly cited 2.5 oz-per-pound guideline, capped at a sensible daily maximum. The Sleep Schedule by Agetool lays out typical total sleep and nap counts by age band, from newborn through the teen years, so you have a rough target to plan bedtime around. Both are generalizations drawn from widely published guidance — every baby sleeps and eats differently, and a pediatrician is the right person to ask if you’re worried about either.
Picking a name
The Baby Name Generatoris the one tool here that isn’t a calculator — it’s a browsable list of popular girl, boy, and gender-neutral names, filterable by starting letter, that you can tap through one at a time to build a shortlist. No algorithm is trying to guess your taste; it’s just an easier way to skim a lot of names.
What raising a child actually costs
The Cost of Raising a Child Calculator takes the monthly expenses you enter — childcare, food, clothing, activities, whatever applies — and projects them out to monthly, annual, and long-term totals through whatever age you choose. The output is only as good as the numbers you put in; it’s meant as a budgeting aid, not a forecast of what your household will actually spend.
Watching development unfold
The Developmental Milestone Tracker lists the motor, language, and social milestones typically seen at each age band from newborn to age five. It describes what many children are doing at a given age, drawn from general developmental guidance — not a checklist your child needs to hit on schedule. Development varies a lot between children, and a pediatrician is who to talk to about any specific concern.
The Childhood & Play Museum
Away from the calculators, the Childhood & Play Museumis a set of galleries on classic toys, family games and puzzles, outdoor and active play, and the tools of early learning. Every entry, image, and fact in it is sourced from Wikipedia and Wikimedia Commons, credited at the source. It’s there to browse, not to sell anything. The Learn section and blog hold longer articles if you want more than a calculator gives you.
What this site is — and isn’t
KidBeast.com isn’t affiliated with any hospital, pediatric association, formula brand, or parenting authority it references — the calculators use commonly published formulas and guidelines, not proprietary data. Every tool here gives an estimate or general information, not medical, developmental, or financial advice, and none of it replaces a conversation with your pediatrician, doctor, or another qualified professional about your child specifically. The site runs on advertising, which is why you’ll see ads alongside the tools; there’s no user count, origin story, or team to point to beyond what’s written here. Questions or corrections are always welcome — see Contact.
