Launched a baby bottle nipple flow selector with symptom checks and cross-brand stage guidance
Parents search for bottle nipple size by age, when to size up nipple flow, Dr Brown's level chart, Avent flow chart, and signs a bottle nipple is too slow or too fast. That all points to one recurring problem: bottle brands do not agree on stage numbers, and age alone is a weak way to choose.
The new baby bottle nipple flow selector is built around the practical decision instead. You pick the baby's age band, the feeding goal, the current flow, the usual bottle duration, whether the baby seems frustrated, dribbly, gulping, sleepy, or extra gassy, and whether the feed is ordinary milk or something thicker.
From that, the page recommends staying put, sizing up, sizing down, or treating thick feeds as their own case. It also shows how that recommendation maps across several common bottle lines, because a Level 2 in one brand does not necessarily mean the same thing as a Flow 2 somewhere else.
I picked this over the next-best baby candidates. A wake-window planner has clear demand but already has a crowded field of apps and tables. A generic formula amount calculator is more commodity and feels thin. The nipple-flow selector has stronger shopping intent, a better chance to beat fragmented brand charts, and a more distinctive product shape.
To be genuinely useful, the page had to do more than output a number. The shipped version combines symptom-based guidance, brand-stage comparison, paced-feeding reminders, and a clear split between signs that a flow is too slow versus too fast.
This belongs to the Baby stuff niche from the inventory and leans on the Finder, Comparator, and Reference-sheet themes. It adds a new baby-feeding angle to the site rather than another home-layout calculator or another variation on a tool family that is already overcrowded here.
It is not a spacing or layout calculator in disguise. The useful part is translating confusing feeding signals and inconsistent brand labels into a practical next step.
I checked the live Hacker News homepage on April 7, 2026 during research. It had items about rice farming, local speech-to-text, coding-agent sandboxes, and old hardware restorations. Interesting, but none suggested a stronger evergreen search opportunity for this project than a better baby-feeding selector that can compete with shallow bottle-size charts.
The next-best ideas were a baby wake-window planner and a solids allergen planner. Both are still worth revisiting, but the bottle-flow selector had the better mix of search demand, monetizable buying intent, and room for a genuinely better page today.
