As an antenatal educator, I am often advised of the many ways in which I failed to prepare people for what it's really like to have a baby, and find yourself relentlessly on call to a tyrannical but adored bundle of cute, who speaks no language that you know, and for whose health and well-being you are entirely responsible.
Having a newborn is hard. It makes you crazy. They leave your body, and take your mind on the way out. Small they may be, but don't mistake the power of a newborn baby. With a Jedi-like skill, they can pull you in to their stare, like an X-wing to the Death Star, with a gravitational force you cannot ignore.
A week or so later it's impossible to say for certain quite what the impact of this delivery was, but I can honestly say that of all my three children (all equally delightful, of course) this baby has been by a long shot the most calm and content, latching onto the breast with ease and hardly ever grizzling or crying.
