Called the on call dr at our pediatrician's office. He suggested offering less liquid more often (as opposed to a half full sippy)...and just a few bites of food - even if he seems hungrier. If it persists, we are supposed to go to the Children's hospital. He really pushed that I should try to get him to keep some liquids down because if I brought him in with his symptoms, they will probably do an IV.
So, we are on close watch for the next few hours and if no wet diapers or still crying without tears - it is off to the ER for us.
