After talking to the nurse we decided to make an appointment for Zak since he was the worst and Ryder really seemed to be ok. Ben took Zak tonight at 8pm to the pediatrician. He just called to let me know they are on their way home and all is fine. What they have is viral and will have to just run its course. The pediatrician also said now that they are getting older hopefully they will be able to fight off these random viral things easier. So we just have to wait and hope they improve sooner than later!
