Aww, mahirap talaga pag may sipon ang bata, lalo na pag 3 years old pa lang! Honestly, a few of us mums swear by saline nasal drops or spray para ma-clear agad ang nose niya, then paracetamol if may fever, pero mas importante talaga yung fluids, steam inhalation, and plenty of rest para bumilis ang recovery.
Since sipon lang usually yan, minsan uwi nalang within a few days, pero if it's been more than a week or may ibang symptoms, definitely check with your pedia para ma-rule out kung bacterial na or may complications na. Laban lang, mommy!
