Unfortunately, NYC subway riding is not easy with the baby, unless you are baby wearing.  Elevators are constantly out of service, stinky and not widely available.  It took me 3 months just to try the subway with Baby O.  The subway is quick and easy when traveling solo but with a babe, it becomes a bit stressful.  Attached is an elevator map to help get you through.  

We live in a very walkable part of manhattan, so I can walk most places within a half hour so we don’t take the subway that often.
