A well-known Moscow pediatrician with a 50-year practice discusses a range of urgent topics that are now relevant both for parents and for doctors: natural/breastfeeding and artificial feeding, preventive vaccinations, accounting for the environmental situation, vegetarian and separate nutrition, therapeutic fasting, and more. In an accessible form, the “Conversations” describe ways to combat the most common childhood illnesses today: dysbiosis, diathesis, ARVI, asthmatic bronchitis, etc. These “Conversations” are intended for a broad readership: from young parents to practicing pediatricians.
