Suggest Treatment For Sever Asthma And Acid Reflux

My daughter is 16 months old and ever since she was born, she has cried excessively at night. She has severe asthma and severe acid reflux. The doctors say that it s not her acid reflux, they have done multiple tests. She s had an EEG which came back normal. They said that they thought she had colic when she was an infant and that she would outgrow the excessive crying, which she hasn t. This is an every night occurrance. She doesn t just wake up a couple of times. This is 10-20 times EVERY night. No matter when she goes to bed, this happens only at night and never during her daily naps. When she cries she arches her back like she s in pain. This has been going on for 16 months now! I need help for my baby girl (and some sleep!)! Please help me!
