This morning, I heard CC crying at 6 am, her normal wakeup time. When I went into the nursery to get her, I found her face-down in the crib! Our little lady had rolled over from her back to her belly for the first time.
Last night after she fell asleep, I continued to her her cry briefly every once in a while until about 11pm. I didn't check on her any of those times, because she would immediately fall back asleep. So now I'm wondering when she rolled over. If she rolled onto her tummy last night, it might explain those brief cries. Or she could have rolled over once she woke up this morning. We'll never know!
