Rest assured, though, because there was already a plethora of evidence that antibiotics are over-prescribed. Consider the following:

Quite often antibiotics don't do any good anyway

Many infections are viral and not bacterial (antibiotics do nothing for viral infections)

Many times doctors have no clue what's causing the infection, yet antibiotics are ordered anyway (broad spectrum).

Many times antibiotics are only prescribed so mom's think something is being done

Or sometimes they're ordered just so the doctor can make sure he covers all his bases

Likewise, abuse of antibiotics has lead to antibiotic resistant bacteria

So the bottom line here is antibiotics may not even be necessary for your infant anyway. If they're in need then they should be used.  But just beware! Antibiotics may, cause asthma.
