How we double-check the food advice in this app
This app tells you things that matter: which foods need extra care for choking, which contain major food allergens, and which carry age-specific safety warnings. You deserve to know how we try to keep more than 1,000 food pages accurate. Here is the system, in plain words.
A computer rechecks every food page before any update goes out
Before an update ever reaches your phone, a program rereads the entire food library looking for the mistakes that would matter most. A few examples of what it insists on:
- Honey must never be listed as okay before 12 months. Ever.
- If a page says “never serve this,” it must also say why.
- Every fish on the FDA and EPA's “Choices to Avoid” list (their highest-mercury category) that appears in our library must be easy to find by the names people actually use, and each one must clearly carry that warning.
- The same food listed under two names must carry the same safety guidance under both.
If any of that is wrong anywhere, the update simply does not go out until it is fixed. Not “we will get to it.” It cannot ship.
A person rereads the riskiest pages on a schedule
Computers catch mix-ups. They do not notice when the official advice changes. So every three months, one of us sits down and rereads the highest-stakes pages, the danger warnings, the allergen notes, the choking-age guidance, the fish lists, against the current guidance from the AAP, the CDC, the FDA and EPA, and NIAID. We made this schedule impossible to skip: if the review is overdue, we cannot publish any updates at all until it is done. Busy months happen to everyone. The block stays up anyway.
When we get something wrong, we say so where you can see it
Every safety and guidance correction goes in our public changelog, in plain words, including what we got wrong. Real examples: sugar apple and soursop were missing a warning their close cousins already carried, and logging oatmeal was wrongly counting as a wheat introduction. Every app gets things wrong sometimes. We publish our mistakes instead of hiding them.
What we will never do
We do not diagnose anything, ever. The app can tell you what you logged and what published guidance says. When that raises a health or safety question about your child, the interpretation belongs with your pediatrician, and our pages say so. One more honest thing: having a pediatric professional independently review our health and safety content is the bar we are working toward, and until a named clinician has reviewed a page, we will not pretend one has. Our editorial policy spells that out.
