Parents follow a guided app to measure growth, track milestones, and log health. A licensed pediatrician reviews every check-in and returns a written summary. Built on AAP Bright Futures and WHO standards.

The annual wellcheck, the global reference for preventive pediatric care, was never the clinical ideal. It was a logistics compromise, built around what a physician could bill for in 18 minutes. A single yearly data point is noise. Monthly measurements, quarterly check-ins, and continuous monitoring are signal.
Balayu is built around that insight. Every child develops a personal baseline from their own data, not a population average. Continuous monitoring catches what's unusual for them. A pediatrician reviews the record on a defined cadence, and whenever anything surfaces. Over ten years, your child's Balayu record becomes a longitudinal developmental biography. The most complete picture of their health that has ever been assembled.
This is not a digital version of the old standard. It is the standard the old standard will eventually become.
You've already been watching. Height marks on the doorframe. Milestones logged in the family chat. The pediatrician call when something felt off. This is what proactive care looks like, and you've been doing the parts of it you could on your own.
The layer above it has never existed for most families. A structured record a pediatrician reviews every month, not only when something is wrong. The standard for children in the countries that built it. Even families who can afford anything have not been able to buy this, because it has not been built.
Harutois developing well. Growth, vitals, listening, and development all sit comfortably within his own pattern. Keep doing what you're doing.
Tracking on the 52nd percentile for weight and 47th for height. Velocity is steady. Continuing along his own curve, which is exactly what we want at this age.
Lung sounds clear bilaterally across all six points. Heart rhythm regular. No murmur on any of the four heart points.
All five ASQ-3 domains in the typical range. Communication and fine motor are particularly strong this quarter.
You mentioned the runny nose last week. From everything I see and hear today, it appears to have been a mild upper respiratory infection that has resolved. No follow-up needed.
Continue Vitamin D3 daily. Keep iron supplement going for another six weeks, then we'll reassess at the next quarterly check.
Routine quarterly wellcheck in three months. Monthly check-ins continue in between, as usual.
Every Balayu wellcheck is reviewed and signed by a licensed pediatrician. Built on AAP Bright Futures and WHO growth standards.
Every reading is measured against two things: your child's own personal baseline, and a growing longitudinal dataset of children's health being built across every Balayu family, the first of its kind at this scale.
Every reading is compared against your child's baseline the moment you submit it, and the instant anything drifts outside what is normal for them a pediatrician is brought into the record within 24 hours. The question of whether a reading is worth raising has never been yours to carry alone.
Every three months, a pediatrician reviews the full accumulated record. Six months of sleep data alongside a slight appetite shift can read as a pattern no single check would flag.
Once a year, twelve months of continuous data contributes to one comprehensive physician review. The result is a longitudinal health record that grows richer every year your child is on Balayu.
