Pediatrician Fyodor Katasonov, author of the popular Telegram channel “Fediatrics,” not only treats children but also comforts their parents by clearly explaining why children's health is much more resilient than their own. Katasonov addresses questions that worry many moms and dads (including expectant ones!): how to prepare for childbirth? How to choose a good doctor? How does immunity work? And what about vaccinations? Reading “Fediatrics” will be useful for everyone who cares about health — their own and their loved ones' — and will also help save your money and nerves. This reissue includes many new updates: in chapters on autism, vaccines, vitamin D, children's checkups, and weaning, the recommendations have been clarified in accordance with current scientific data.
