My 3 month old baby has an umbilical granuloma which isn't healing. Health visitor and Dr told me to clean with cool boiled water. It has discharge in every day, and in the last week has bled (a very small amount) twice. Had call from Dr's yesterday afternoon to confirm it is now infected, so he's been put on antibiotics. Any tips on how to get it to heal after infection has gone? Don't feel the cool boiled water is enough..
