Sleeping Woes

Yes, it is almost 0600 and I am still awake for a number of reasons.

Ry is on graveyard this month, and I always hate it. Not only do I have to sleep alone - which usually doesn't go great because, well, he's not here - and when he gets home he has to sleep while the baby and I quietly play downstairs. The second problem is that Sam's sleeping schedule is all sorts of messed up. It just started a few days ago; her usual bedtime is between 2100 and 2200. It has been slowly creeping up and last night/this morning she did not go to sleep until 0300. I tried everything. Not only is she not going to bed at a decent time, she is also sleeping like a newborn. She used to take about thirty to one hour naps every two or three hours. Now she is sleeping two, three sometimes four hours at a time. I know what you're thinking: just wake her up. That would work if she actually agreed with that, but you wake her up before SHE wants to and we get crabby, stubborn Sam.

I just don't know what to do. We try baths, feeding her really well, and everything you can think of. She's cutting her first tooth but it doesn't hurt her, as she is extremely bubbly while awake. Is excess sleeping attributed to that? Perhaps her Prevacid (Reflux Med)?

I think it's time to go google, since I can't sleep anyway.

***Update***

I read up on it and neither of the above mentioned have anything to do with her sleep patterns. I need some good advice on this one.
