To Sleep or Not to Sleep?...I wish it weren't a question

So after two months of Lauren sleeping through the night and then out of no where three weeks of her waking up every hour or two I was starting to go a little crazy.  It was still another month until her 6 month check up and I didn't want to wait that long to get her to start sleeping again.  So I went to the library and got a bunch of books  about getting babies to sleep.  Turns out she just needed to go to bed way earlier, so we've started a little bedtime routine and put her down at about 7pm every night.  She's been doing it for about two weeks now and it has made a world of difference.  It took a few nights of letting her cry herself to sleep, sometimes for nearly an hour, but she goes down pretty quickly now and she sleeps about 7pm to 6 am.  The sleep schedule works out pretty sweet for all involved, I'm getting way more homework done, just in time to save my grades this semester (hopefully).
  We are now in the process of attacking Lauren's nap schedule, which until this point has been pretty much non-existent.  She has never really been one to take naps, even when she was just a few weeks old we'd be lucky if she went down for an hour or two.  It's coming along pretty slow but I think she is starting to realize that she needs naps.

So when she doesn't take naps she goes a little crazy.  She will laugh her head off at everything for a while and then start screaming.  This is the state I found her in about a week ago when I got home from class.  It was around 5pm and she had decided to continue her nap strike that day... she usually doesn't even think this game is very funny...
