About GetBabyReady

GetBabyReady is a small independent site that builds free calculators for the practical, countable parts of having a baby: how much things cost, how many of them to buy, what size fits, and when a food is safe to introduce. It is aimed at expecting and new parents in the first year — the period where almost every question has a number attached to it and almost none of the answers are easy to find.

Why the site exists

Search for "how many onesies do I need" and you get a dozen articles that each state a confident round number, none of which agree, and none of which say where the number came from. Search for "when can babies have honey" and you get the right answer buried in a listicle wrapped around an affiliate link. The information exists — the American Academy of Pediatrics, the CDC and the manufacturers all publish it — but it is scattered, and the sites that aggregate it rarely tell you which parts are established guidance and which parts are somebody's guess.

GetBabyReady is built by a parent who has been through all of it — the newborn weeks, the sizing, the feeding arithmetic, the first foods, and the registry decisions you only get to make once. These were our own questions before they were tools. Each one takes the details of your situation, applies published guidance where it exists, and shows the arithmetic where it does not.

The rules we work to

• Every number is sourced or shown. A figure on this site is either published by an organisation we name on the page, or it is arithmetic we lay out so you can check it. There is no third category.
• Where nobody publishes an authoritative figure, we say so. Nobody publishes an official "you need eight bodysuits". Rather than invent one, our newborn calculator asks how often you do laundry and multiplies it out, and the result labels those rows as our estimate rather than a published rate.
• Safety guidance is never softened to sell something. On any page where the answer is "not yet" or "never before twelve months", the buy links are suppressed in code, not by editorial habit. An automated check runs on every deploy and fails the build if a page states a hard safety rule while carrying a purchase link.
• We publish our gaps. Where a source was unreachable, where a figure is interpolated, where a manufacturer's chart disagrees with another's — that is written on the page next to the number, not hidden in a footnote.
• Nothing is stored. The tools run in your browser. We do not ask for an account, and the details you type about your baby are never sent to us.

Where the data comes from

The sources differ by tool, and each page names its own. Across the site they are:

• American Academy of Pediatrics — infant feeding amounts, the early-allergen-introduction guidance, and the safe-sleep policy that drives every crib and sleep recommendation.
• Centers for Disease Control and Prevention — solid-food introduction, foods and drinks to avoid or limit, choking hazards, and the urgent maternal warning signs reproduced on our postpartum page.
• Cleveland Clinic and UT Southwestern Medical Center — the at-home recovery measures and hospital packing guidance.
• Manufacturer published charts — Pampers for diaper sizing and usage rates, Gerber Childrenswear and Burt's Bees Baby for clothing sizes, Enfamil for formula mixing ratios and can yields.
• FDA and EPA — the joint advice on fish and mercury.

Where two sources disagree, we show both rather than picking a winner quietly. Our clothing size tool publishes two manufacturers' charts side by side precisely because they differ by up to a pound and a half at some sizes, and that gap is real information.

What this site is not

It is not medical advice, and it is not a substitute for your pediatrician, midwife or obstetrician. The tools are reference and planning aids. Where a question is genuinely clinical — how your own recovery is going, whether your baby is feeding enough, whether a symptom needs attention — the honest answer is to call your provider, and the pages say so rather than guessing.

We also do not review or rank baby products. Some pages carry affiliate links to general categories of gear, disclosed on the page, and those links never change an answer or appear alongside a safety warning.

Corrections

If a figure here is wrong, out of date, or contradicts a source we cite, we want to know — and we would rather fix it than defend it. Guidance in this field genuinely changes; the advice on introducing allergens reversed within the last decade. Every page carries a last-updated date, and you can reach us at our contact page.
