Newborn kittens can crawl, killer whales can swim, and elephant calves can walk. A human baby is born unadapted and requires enormous resources in the first year of life. Raising a healthy and happy person - and at the same time not losing your career, well-being and peace of mind - is a colossal job, despite advances in medicine and rising living standards. As a result, many decide not to have children at all: everything is complicated, and there are already almost 8 billion of us on the planet. Scientific journalist, science popularizer and young mother Asya Kazantseva would have been very surprised if five years ago she had been told that she would want a child so early. This book of hers, her fourth, is special: in it the author, as always, professionally and entertainingly, talks about recent research in the field of embryology, neonatology and in vitro fertilization; about real and mythical risks for mother and fetus; about the possibilities and limitations of modern medicine. But that's not all. It is also a personal story of the most important decision in life and the beginning of a great love. The publishing design is preserved in PDF A4 format.
