Refresher course in sleep.

I think Logan needs a schedule change but, I have no idea how to go about it. She will not sleep at night. She'll go down between 7-8.30pm. She's up at 11.30pm (last night until after 2am) & again at 5am. She used to take a morning nap from 7am-9am but, now she will only sleep for about half an hour. This weekend she had decided that naps were so not cool & stayed up from 5am to about noon & then slept for 2 hours. Yesterday she did her normal two 2 hour naps.

I have had 8 hours of sleep in the past 2 days.

I have to do something. I cannot function like this. It's getting close to impossible. I'm cranky. I have no energy. I'm on the verge of passing out at 5pm every night. *sighs*

My 8 month old has forgotten how to sleep.
