Kathleen,
If you will look at The happiest baby on the block, you can get it free at the Library, it really will help you to solve these problems. Babies need us at first and cry to let us know. Helping them to find the soothing of the safety of the womb helps them to feel safe and comfortable. That includes swaddling tightly so thier arms can't get out, white noise very loud, often continous movement. All put together it works well but it needs to be in the right order and consistent.
email me off group for more information.
