Brakes or Baby?

Elynor actually went back to sleep after her middle of the night feed last night - YIPPEE! The only problem was that I struggled to do the same. Instead of enjoying this precious gift, I laid in bed wide awake, on high alert for her to scream. During this time there were several instances where I thought she had squealed, only to realize it was some squeaky brakes on a passing car or bus. I guess this is just another one of the joys of parenthood on a moderately busy city street. Even at 4am cars are driving by with annoying brakes.
