We recently realized that Max has a 'sheet preference' and that change in said preference messes with his sleep patterns.
One night last week while I was bathing Max, Michael went to change the sheet in Max's crib. It was white with a speckled dot pattern. As he was changing it, he had an 'Ah-ha!' moment. (This kind of 'Ah-ha!', not this.) He noted aloud that Max had recently started waking up at least once in the middle of the night, which was very unlike him since our hard-earned victory in the Sleep Wars. As a designer, he knows to veer away from using blue, as it lulls people to sleep.
The previous bed sheet had been- you guessed it, BLUE. And Max had been sleeping like a champ... when he was on the BLUE sheet! (Coincidentally, just the previous evening my friend Betty had been talking about how she had the same fiasco with her daughter- changing from a solid pink sheet to pattern.)
So we went back to blue and wouldn't you know it? He's been sleeping like a... well, like a baby ever since! Ta-da!
