She seems to be having viral infection.Crocin
you are giving is for fever
, it will not give any relief in cold
. She may not sleep comfortably because of block nose and as she fills not well she may be screming.You give anticold syrup for this, and give her hot liquids like soups etc, which will cause decongestion and comfort her.In other case give crocin in dose of 15ml/kg per dose upto 3-4 times in day,normal syrup contains 125mg/ml.
