Sources and limitations
This page explains where the specific information in this reference comes from, how we decide what to publish and where the usefulness of a text on a website ends. We have only a few sources, and that is deliberate: when it comes to children's health, accuracy and caution matter more than volume. Anything that requires examining and assessing a particular child we leave to the paediatrician, and when a life is in danger, to emergency services (112 and 103 in Russia, 112 across the EU, or your national number).
This reference cannot see your child. So the most honest thing is to say plainly what it can explain and what remains the doctor's job.
How we select sources
We give guides on sleep and physical activity for children under 5 according to the 2019 World Health Organization guidelines, and for children and teenagers aged 5–17 according to the 2020 WHO guidelines. There are no other figures on sleep or activity in this reference.
On vaccinations, we say only that Russia's national vaccination schedule was approved by Russian Ministry of Health order No. 1122n of 6 December 2021. We do not summarise the list of vaccinations or their timing: how they apply to a particular child is discussed with the paediatrician. Other countries have their own national schedules, and readers there should follow their national health service and paediatrician.
On routine check-ups, we mention that in Russia their procedure for minors is set by Russian Ministry of Health order No. 514n of 10 August 2017, without giving a month-by-month visit timetable; other countries run their own check-up programmes. We do not treat social media summaries, personal stories or anonymous advice as sources.

Limitations of this reference
Zdravdeti is not a medical organisation, clinic, hospital or government body and does not speak on their behalf. We do not give consultations, make diagnoses, name medicines, doses or supplements, or describe treatment plans.
We do not argue about vaccinations or discourage them: decisions about vaccinations and any doubts are discussed with the paediatrician. We do not advertise clinics, medicines or children's products, and we do not collect money.
The text helps you understand general guides, settle a daily routine and prepare for a visit to the doctor. It does not teach first aid and does not replace an examination. If your child's life is in danger, call 112 or 103 in Russia, or your local emergency number elsewhere.
