Well I found a place, it's dark and it's rotted

Dear Internet,

Please, help! I'm at my wits end! Last night was better, a little better, but bed time was still a nightmare. I kept Mary up quite a bit yesterday, I only allowed her an hour and a half for naptime (she only naps once a day). I stuffed her full of food so she wouldn't wake up hungry. Ian kept her up quite late last night also, till about 8:30. She was tired. She was so freaking tired. But when we put her in bed, she screamed. She wouldn't take her bedtime bottle, she just screamed and screamed. It wasn't the fussy, crabby scream. It was the "Oh my God, I've been abandoned, someone killed my cats and my toenails are being torn out one by one" scream. I finally got her to sleep in my arms by cuddling her, I held her while I gave her the bottle which she really wanted, but wouldn't take in her bed like she usually does. She went to bed at about 10:30, screamed for 10 minutes and finally fell asleep.

So, here is my question. What would cause a baby to act like this? For the first year of her life she slept like an angel. Is it even possible for a one year old to be afraid of the dark? She has a night light, always has, but I just dont know. Could it be separation anxiety rearing it's ugly head? What is she so afraid of at night in her bedroom? Nothing's changed in there at all. Sigh. I'm just totally stumped by the whole production.

I do still have to post about the Christmas Blogstravaganza soon. This afternoon or evening if I get a chance.
