My baby girl has been sick for four days now :(?

When you have a young child my best advice is to take your child to the Emergency Room or your Doctors. There are no Doctors on this site and the information you get be dangerous for a child. I have been in nursing for over twenty years and I wouldn't even give you any medical advise. Children have special needs. This is YOUR BABY! And you want the best for him/her. This baby sounds very sick and you need to seek medical attention,right away.
