Most babies I heard of that cry a lot have some wind in their tummies... How's your baby burping? Do you have problems burping her?
When my son was like that, we had to keep trying to burp him which can take up to 10-15min. In the end we brought him to see a pediatrician where he prescribed colic drops for my baby. At the same time we also used "Ru Yi" oil to rub his tummy (just 2 drops of the oil). After that he got better.
