Down here a child under 3 months with a temp over 37.5 is considered to have a fever and your supposed to bring them in now after the 3 months you give them 2-3 days unless it over 103 (can cause seizures) that is why they recommend this. There is not much you can do for a cold or flu because its viral but you can help with symptoms here are other things you can try
~gerber/johnson &johnson vapor bath
~tylenol for fever
~saline drops
~something to clean out babys nose
~humidifier (or fan/window open_)
after 3 months (unless recommended by dr/pharmacist)
~dimetapp cold & fever
!~vicks
there is other stuff im just really brain dead (forgetting everything lol_) so ill update later! This info is from hubby(rn) or from local childrens hospital.
Take care
