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 shows the American Academy of Pediatrics’ published formula average for a baby’s weight, for comparison only, beside the FDA, CDC and AAP facts every bottle needs; it never gives an amount per bottle. The Sleep Schedule by Agetool shows the American Academy of Sleep Medicine’s total sleep ranges from 4 months through the teen years, with the AAP’s safe sleep rules for every baby under 1 year. Every baby sleeps and eats differently, and your baby’s doctor 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 shows CDC’s Learn the Signs. Act Early. milestone checklists, word for word, for 12 ages from 2 months to 5 years: what most children (75% or more) do by each age. It never scores a child. CDC says not to wait: if your child is not meeting one or more milestones, has lost skills, or you have other concerns, talk with your child’s doctor and ask about developmental screening.
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.
