S.H.
YES, there is something going around, in my city.
Kids and adults are getting sick.
Flu like symptoms.
Just like your baby has.
I also work at my kids' school, everyday, kids are going home sick. With that same bunch of symptoms.
Being your child is very young, you have to keep an eye out. Dehydration can occur again. Keep him hydrated. Little amounts of water at a time. Not all at one time.
Just eat as he feels like it.
Bland foods.
My friend had it for a whole week and missed work and took her another week to totally recover.
I had it too.
My son had it too.
My daughter too, but to a lesser degree.
Also look out for worsening symptoms in your child, and/or mucus coloration or Fever.
Per Flu "Facts": it has
F= Fever
A= aches
C= Chills
T= Tiredness
S= sudden onset
This is what differentiates it from a "cold."
