Mommies, hello! I'm sharing some news - we went to another pediatrician, overall, with the umbilical cord everything is fine, as it turned out we have low weight (6400). She said to take an analysis for anemia, maybe that's why there's no appetite. Maybe someone had anemia in their kids? Is it dangerous? Just my daughter has started being capricious and quickly gained weight. Well, she said to start feeding her porridge to gain weight.
