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.

How we count

Two of these are not editorial promises — they are assertions an automated check makes on every deploy, and the build fails if one of them stops being true.

1. 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.
2. 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 labels those rows as our estimate rather than a published rate.
3. Safety guidance is never softened to sell something. Enforced in build On any page where the answer is "not yet" or "never before twelve months", the buy links are suppressed in code. The deploy fails if a page states a hard safety rule while carrying a purchase link.
4. No advertisement or affiliate link appears above an answer. Enforced in build The result renders first; the monetization slot does not exist until there is a result above it.
5. We publish our gaps. Where a source covers a category but not the specific food, the page says so in a panel rather than a footnote. Where a figure is interpolated, it is labelled next to the number.
6. 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.
7. Medical authority is deferred, never assumed. Feeding, food-safety and sleep guidance comes from the American Academy of Pediatrics and the CDC, and we say which. This site is not a clinical source and does not present itself as one.

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.
