how to comfort your toddler?

hello, mommies, yung toddler ko kasi is currently suffering from her allergic rhinitis and constantly crying kasi sneeze siya ng sneeze tas syempre pag constantly pinupusan ang ilong sumasakit so iniiyakan niya yon kasi need naming punasan kasi tumutulo yung sipon niya. We already gave her antihistamine but wala naman masyadong relief. Do you guys have any tips po? Para macomfort or marelief si LO kahit papaano...
