My son is a week and a day old he got circumcised when he was two days old. He received a plastic piece on there and I was told not to use ointment or wipes on it because it could cause the plastic to come off. Also said urine was sterile, and not to really do anything to it. This morning I noticed like a blood bubble below the circumcision and a tinge of yellow not puss though. He s bit running a fever and he s acting ok. Please help, I m a worried mother. Thank you
