Two days ago my daughter starting crying for no reason. She was up for most of the night and pretty much cried for all of it. It is an agonizing cry and it seems to be coming and going. I took her to see a Dr and had her ears, belly, throat and urine tested to which results were negative. Last night she was up most of the night and still feel the same way this morning. ANy suggestions. I will be taking her to a dr again today
