So I did it, I jinxed myself with my last post. Last night Campbell went to bed, as usual, but it didn't last. He woke up at 12:30, crying, so I fed him. He then played in his crib, singing and jabbering away, for about an hour before starting to cry again. I fed him again, and we both finally went back to sleep. I hoped he'd sleep late this morning, but no such luck. He woke up at 6:00, ate and refused to go back to sleep.
It just goes to show you, it's always something.
