Hi Lakisha,
I was wondering if she was truly comfortable throughout the night. If she is wet, she will not be comfortable, and thus she'll be fussy. Take a look at this: http://cheerfulaboutanions.yolasite.com/. The demo is on products for women, but there are diapers that will be available in about 1 month, with the same technology that is shown in the demo. The number one thing consumers look for in any type of sanitary product: protection-super absorption so effective that there is no wetness next to the skin even after a full day or night of wear.
I went back and looked at your message and it seems like you are saying she is waking up during the night, screaming for you. I double checked because I wanted to be sure she wasn't just fussing from the time you put her down. It may well be that she is wet during the night and is feeling uncomfortable.
Another benefit of the product in the demo is negative ions. These have a balancing effect on the body, so I'm sure this product could be useful in calming her. Negative ions can be used to treat illness and improve health.
To show you just how powerful this technology is, please look at this: http://www.youtube.com/watch?v=sI8z5pIPE44.

Also, concerning the milk, I'd like to suggest a book called Fit for Life. It talks about milk and especially cow's milk and its effects. If you are giving her that, she may have indigestion, or even bloating during the night from gas. If you are going to give her milk, I'd suggest one of the natural ones from plants like oat, almond, rice milks.
Also, a health food store like Whole Foods Market will have baby cereal that is like cream of wheat, cream of rice etc. I don't suggest the wheat because it activates sinus issues, but the cream of rice is great.
You can put it in the milk (rice, almond, goat, or oat as suggested below) and it will fill her up for the night. She could be just getting hungry because if you put her down at 7 or 8 pm, she would have to sleep almost 12 hours if she was getting up anywhere between 6am and 8am. That's a long time, and she may be getting hungry. If she doesn't fall asleep until almost 10pm, have you tried putting her down at that time with a full bottle? It may work.
Good Luck, and let me know if I can assist you in any way.
