Hello Do not remove the earring immediately unless there is significant swelling or pain — this may trap the infection Avoid touching or rotating the earring frequently Betadine Ointment 5% (Povidone-iodine 5%) Avoid: 10% solution — this is typically the liquid antiseptic solution, not the ointment, and may be too strong for infant skin, especially on delicate areas like the ear. Consider Oral Antibiotics if: Redness, warmth, and swelling are spreading, Baby has fever, irritability, or poor feeding, Lesion is large or not improving in 2 days with topical treatment

10% ointment is enough

It’s common for ear piercings in infants to develop mild infections, especially if a pus-filled blister appears. You may gently clean the area with mild soap and clean water, then use Betadine ointment—10% is safe for topical use, but apply only a thin layer and avoid excessive use, as too much may irritate sensitive baby skin. However, in infants this young, skin reactions are more likely, so I recommend using minimal ointment or even just saline washes unless otherwise directed by a doctor.
