So looks like our mission was accomplished.
Except in the process, it failed to dawn on me that without a pacifier to suck on he wouldn't be able to fall asleep on his own.
After being asleep for almost 2 hours he woke up hysterical at 8:45pm with no comfort from the now-cut pacifier.
So while we didn't want to attempt Ferber after the weekend's tears, we now have to find a way to put him to sleep without creating a new crutch like nursing or rocking to sleep.
Fun. Hadn't really planned on this being in the cards for tonight's itinerary!
