Hi mommy! Please see your baby's doctor or go to the nearest clinic/hospital muna, especially with a one-month-old, it's really important to get checked properly, ok? A blocked nose sa ganitong edad ay dapat tiningnan ng pedia para sure na okay lang siya at walang ibang problema. Ako rin, when my baby was that tiny, I didn't want to take chances kahit small concern lang. Mas peace of mind, and the doctor can tell you exactly what's safe for baby at that age. Praying for your little one, mommy!
