Hi, I am having a 3 years old daughter. She is usually very active. Till she woke up she was okay and she had her morning break fast without any problem. She was even playing very well after that. But then she started having her bowel movements(stools) very loose. And then she started crying with stomach pain. Then all of a sudden she got high fever. I am not sure what the problem is. Just for a note, She is still having her thumb sucking habit. I am really wondering is it because of poor hygiene?
