Our daughter Aaru arrived in May. Within a week, my wife and I hit the same wall every new parent hits: a phone full of half-trustworthy search results at 2am, and no good way to tell signal from noise. You are tired, you are worried, and the internet is happy to make both worse.
So I built something.
The constraint that made it work
The whole app rests on one rule: every answer is grounded strictly in American Academy of Pediatrics guidance, and nothing else. No forums, no SEO sludge, no confident strangers. That single constraint is what made it trustworthy enough to actually open at the worst hour of the night. It also made the product simpler to build, because I was not trying to boil the ocean. I was wrapping one good source in a calm interface.
What it does
Manasa and I can ask a question in plain language and get an answer pulled only from vetted pediatric guidance. We can upload Aaru's records as PDFs when a question needs context, and the app keeps a running log of her growth so the numbers live in one place instead of scattered across a dozen forms.
The stack
Next.js on Vercel, Postgres for the growth data, Blob for the uploaded records, and a shared family login so it is just the two of us. The model does the reading and the careful phrasing. The constraint does the trusting.
What I would tell another builder-parent
Start with the smallest version that earns trust. The fancy features can wait. The thing that mattered at 2am was not breadth, it was knowing the answer came from somewhere real.
