My five year old son started out with a nasty cough yesterday morning and now he still has a nasty cough is a bit wheezy complaining of a sore throat and has just woke up to a fever of 103.7!! Is that too high for his age?? When should i be worried and take him to ER?? Hes not very fussy about it hes just very tired. What should i do? Ive already gave him ibprofen. I want to get this fever broke and am trying to keep him away from his baby brother (hes only 7 weeks) any advice please!!!
