Hi Marlea - and welcome!
Sorry to hear you are having such problems with your DD.
Tannis' idea about wrapping (tightly) is a good one. I did that for a while and it worked.
Obviously she's on formula (like mine) - how much (ml) are you giving DD each feed & how old is she? Have you tried to change formulas? Maybe the one she has disagrees with her and upsets her tummy? Talk to your maternal nurse or GP about that before you change though.
How does she sleep & act during the day?
I guess the key is to try and work out why she is so upset... hungry, hot, cold, overtired, reflux or colic... (the list seems endless).
A number of people have suggested Chiropractic for my son (who was a nightmare sleeper). Apparantly that can work wonders. A nice thing you can do for her is give a baby massage twice a day. Any 'natural' oil will do (ie: even cooking oil, jojoba, almond etc... don't use 'J&J baby [mineral] oil'
I was able to get into sleep school - and learnt a few settling tips that have been really handy. He wouldn't go to sleep, and would get so overtired in the evenings. Eventually he would cry himself to sleep as he was so exhausted (around midnight). Now I notice his "tired signs" and put him in his basinette awake. Sometimes I have to pat him or rock him a little while... but he goes to sleep fairly quickly. After a week of this, most of the time he just goes to sleep by himself without rocking/patting.
He had small dummies that would fall out and upset him. So sleep school suggested I get the bigger dummy with the round knob on the end. These have been much better.
I am trying to increase his night time feeds so that he sleeps longer through the night. He has got to a 5 hour sleep which is great - but I don't go to bed till late, so I miss the opportunity to have a 5 hour sleep!
Pinky McKay has a new book on baby sleep - it may be worth picking that up and reading through. She has some nice ideas and is into comfort parenting rather than controlled crying.
Can you book in for a sleep school near you? Ask your maternal nurse or hospital for details. They are a blessing!

Hope that she settles soon.
I understand how you are feeling... and sometimes the only thing that kept my hubby & I sane was knowing that it wouldn't last forever!
