Cameron was yawning and clearly tired, but just would.not.sleep.
Finally, after a second feeding (since I had been trying to get her down since the last feeding, 2.5 hours ago) a third diaper change and second attempt at the swing, I think she's finally sleeping.
My arms are killing me from rocking her for a few hours. I think I need a nap!
Thankfully, she sleeps well at night, but wow....
