Babies need blood sugar (glucose) for energy. Most of that glucose is used by the brain. The baby gets glucose from the mother through the placenta before birth. After birth, the baby gets glucose from the mother through her milk or from formula, and the baby also produces it in the liver.
The Slavs are an Indo-European ethno-linguistic group living in Central Europe, Eastern Europe, Southeast Europe, North Asia and Central Asia, who speak the Indo-European Slavic languages, and share, to varying degrees, certain cultural traits and historical backgrounds.roto-Slavic, the supposed ancestor language of all Slavic languages, is a descendant of common Proto-Indo-European, via a Balto-Slavic stage in which it developed numerous lexical and morphophonological isoglosses with the Baltic languages.
Some authors have traced the origin of the Slavs back to indigenous Iron Age tribes living in the valleys of the Oder and Vistula rivers (in present-day Poland and the Czech Republic) around the 1st century CE. This is, however, still a matter of debate. Based on archaeological evidence, we know that Proto-Slavic people were already active by 1,500 BCE within an area that stretched roughly from western Poland to the Dnieper River in Belarus.
