Sleeeeeeping... or not!

Well, my child USED to sleep for at least 10 hours at night... until, until...

I don't know what happened.  Lena would go to sleep so easily, at 7pm, every single night (and she still does, for the most part), and sleep until at least 6am every single morning.  From about 3 months until about 8 months. And now?  Now, she still goes down pretty easily, but she wakes up between 3 and 4am, talks to herself in the crib for an hour, then begins screaming.  I try to let her just cry for a little while, but my husband and I both want our sleep, and we both know that if I just go in there and rock her for a few minutes she will go back down.  UGH!  What to do???

I know, I know, I KNOW!  Every single parenting thing that I have read (and her pediatrician) tells me to let her cry, let her cry.  I try, I try, I TRY!  It is so frustrating to listen to her cry for an hour, and listen to my husband complain about not sleeping for an hour (when I know he has to get up and go to his 'real job' all day).  When I know that if I just go rock her for a few minutes she will go back down.

On the bright side, she did actually sleep at DayCare yesterday, only for an hour, but she did sleep.  She came home and took a four hour nap, which was glorious!

I gotta go... I need a nap!
