Hello girls. Yesterday we went for a walk with our daughter for about 20 minutes and when we got home, her hands and feet were frozen. The next day she had a fever, a stuffy nose, and a hoarse voice. Ibuprofen helped with the fever. She slept well, but today the fever rose again and her nose is still stuffy. ?? What can I give her? I don't know anymore. I blame myself and hate myself ?
