So I realized in re-reading my swaddling post that perhaps I should clarify one important point:
The swaddle is perfected. Sleep? Not so much.
Swaddling seems to have convinced the babies that their crib is NOT the devil. Convincing them that a full night of sleep would be far more satisfying than a night spent chowing down at the boob-buffet seems to be a different story entirely.
I feel the need to point this out so that when I go back to blaming all of my bizarre behavior on my lack of sleep, nobody calls the validity of that excuse into question.
In short? Swaddle = crib. And "something" = sleep.
I just have no idea what that "something" is.
