Built for 3 a.m.
It is 3 in the morning. The baby has been crying for an hour, your phone is the only light in the room, and the internet is offering you either a research paper or a panic attack.
Peanutbean exists to be the third option.
We take what the actual evidence says, the CDC's milestone checklists, NHS guidance, published studies, and translate it into plain language you can read with one hand while holding a small, loud human. The short answer first. The source linked right there. No jargon, no guilt, no alarmism.
What we promise
Every claim has a source you can check.
Not "experts say." A named organization or study, linked, on every page. If we can't source it, we don't say it.
Honesty about what science doesn't know.
Where research is mixed, we tell you it's mixed. Fussy phases are windows, not appointments, and we say so every time.
Every baby on their own calendar.
Born early? Our forecast runs on adjusted age, the same fair measure doctors use. Comparison is the thief of joy, especially in baby groups.
Calm is the product.
We will never sell you fear to keep you scrolling. The goal is that you close this site feeling better than when you opened it.
Why "Peanutbean"?
Peanut and Bean are the two nicknames almost every baby gets before they get a name, often at the very first ultrasound. Our two mascots have been hugging it out ever since. They are a daily reminder of what this site is about: small humans, held close, doing fine on their own schedule.
What we are not
We are not doctors, and this site is not medical advice. It is the well-organized, properly sourced background reading that makes your conversations with your pediatrician better. When in doubt, call them. Your own concern is always reason enough.
