Kathryn sick

Not sure what is going on with angle face but she woke up Tuesday morning sick and kept us up for several hours. By Friday I thought she was getting better we were even able to do some school work. But today after the parade she started throwing up again. I think if she is not better by Monday I am going to take her into her doctor. I thought it was just a cold but she is complaining of her tummy hurting and there is alot of throwing up. If anyone has a homeopathic recipe to calm a tummy ache or reduce a fever please let me know.
