Waiting for the other shoe to drop

Abby will be one week old tomorrow. She has slept long and peacefully every night so far. Owen was a great sleeper, but there were some fussy nights (and early mornings) out of the gate. This, we learned, was typical newborn behaviour. All first-time parents soon learn that the expression "sleeping like a baby" is a cruel hoax. But Owen settled into a good sleeping pattern, with two short feeds, within a couple of weeks. That became one feed by about a month. Abby seems determined to one-up her big brother already. Two short feeds last night, only one the night before. It can't last. Can it?
