colicky babies?

Thalia • Baby #2🤗
Do any of you ladies have or had a colicky baby and how do you comfort them? I think my daughter is a colicky baby nonstop crying no matter what I do she stops for awhile then continues all over again. Took her to the ER and they said she's fine but her pediatrician says she's not. Idk what else to do. I'm up 4or more hrs trying to stop her crying 😩😩
