Ear infections ?

So.....they say if you have a fever you are contagious to others , right? I have heard that ear infections are not contagious. So.....If fever is a symptom of ear infections, how is it not contagious and not passed to other children . Also if they are not contagious then why do so many children get ear infections around the same time in child care facilities ? Someone help me please!

Car seat TERROR !

I am new to the game so any and all advise is pretty much welcomed at this point. My son is 3 months old now and has started crying like I have just beat him when I put him in his car seat. It is very upseting and embarrising at times.It normally only lasts a few moments but it sounds like a cry of TERROR ! I have checked to make sure it is comfortable and clean .I have attached toys to it. I have played with him in it and nothing seems to be working. Please help !
