How we check our facts
Peanutbean turns official health guidance and published research into plain language parents can use. In a topic like your baby's health, trust is the only thing that matters, so here is exactly how we work, in the open.
Where our facts come from
We build every article from primary sources: the CDC's milestone checklists, the UK's NHS, the American Academy of Pediatrics, and peer-reviewed studies. Every factual claim links to its source right there on the page, so you can check us yourself. If we cannot trace something to guidance like this, we do not say it.
Who writes this
Every article is written and researched by Ciprian H., the parent behind Peanutbean. His background is in engineering, geology, and IT service management, not medicine. That experience is relevant to the way Peanutbean works: start with evidence, document each claim, track changes, and correct mistakes. It is not a substitute for clinical expertise. You can check his professional background on LinkedIn. Peanutbean does not use invented "medically reviewed by" credentials. Every factual claim must trace to a named source and be checked against it before publication.
How each article is made
The same steps, every time:
- We gather the facts from the primary sources above and note the citation for each one.
- We write a draft, then rewrite it in plain language: the short answer first, no clinical jargon, nothing that reads like a textbook at 3 a.m.
- The whole thing gets reviewed against the sources before it goes live. Nothing publishes on autopilot.
- We stamp each article with a "last verified" date and revisit it when the guidance changes.
We tell you when the science is not settled
Some things genuinely are not certain, and we say so on the page instead of pretending otherwise. For example, the popular idea that babies go through fussy phases on a fixed weekly schedule came from a small 1992 study; later research could not confirm the strict timing. So we describe fussy windows, not fixed dates, and we link both the original research and the studies that questioned it. Windows, not verdicts.
What this site is not
Peanutbean is an independent information site, not a medical practice, and nothing here is medical advice. It does not diagnose, treat, or replace your pediatrician. If you are worried about your baby, that is always reason enough to call your doctor, no checklist required. We do not sell your data, and we are not paid to recommend any product.
Fair to babies born early
Development follows the due date, not the birthday. Wherever it matters, we use adjusted age, the way pediatricians do, so premature babies are measured fairly. More on that in our guide to adjusted age.
Real words only
As the site grows we will share what parents tell us, but only real messages, with permission. We do not write or buy testimonials.
Found a mistake? Tell us.
We would rather hear it than miss it. If something looks wrong or out of date, email us at hello@peanutbean.com and we will check it against the sources, fix what needs fixing, and update the date at the top.
