At eight weeks, a human embryo is the size of a kidney bean and has a beating heart. I know this, because I saw an ultrasound of one this week. According to my copy of What To Expect When You’re Expecting with its broken spine and rippled pages, if my book was a human baby, I should be getting plenty of rest, encouraging other people in the household to make me breakfast, and adopting a manageable exercise routine. When my copy of How To Be An Author arrives, I’m going to compare their advice. Either way, breakfast in bed sounds pretty good if I can swing it.
