Last night, in the fog that accompanies half-sleep and 2am, I tried to calculate the odds that we’d have a night in the near future where both kids slept through the night without requiring any assistance. The Little Boy had been doing very well, but a newfound interest in trying to crawl and some teething have put him down at something like a 90% chance of at least one wake-up. The Little Girl hasn’t been terribly interested in sleeping for quite a while now, and her rate of wake-up is probably somewhere in the 70% range. Taking them together, on any given night, we have just a 3% chance that neither child will awaken in the night and need a change or a bottle or a cover or whatever. That’s how I spent my wee hours.
