It’s normal for bcg injection. My baby also had it when she was around 12 weeks old. At her 1 month checkup PD told us that it would happen and no need to do anything. Just keep the area clean and dry will do.
Then it’s normal to have pus. It took my baby more than 4 months to dry up. I put small, waterproof handiplast on it before bathing my baby (when she’s about 4months old). It helps to keep the area dry.
