Oh no! I'm glad she's asleep now.
Was just wondering, are you feeding her at 5:30am? If so, have you tried putting her back to bed after this and seeing if she'll just go back to sleep? This is something I tried when DS was little and was rising really early. I thought he was wide awake for the day but someone suggested I try resettling after the BF and lo and behold he started going back to sleep!
