Australians are taking more and more antibiotics, which has led to some bacteria becoming resistant to antibiotics. In fact, two-thirds of babies of babies have already received antibiotics by the time they are 12 months old. That's according to Dr Penelope Bryant, a Consultant in Paediatric Infectious Diseases and Medical Lead at The Royal Children's Hospital in Melbourne. And while Penelope says there are definitely times that antibiotics are required and life-saving, we need to be more careful about how often they are prescribed to babies. Penelope talks about the risks of antibiotic use in young babies, and how parents can make sure they feel empowered in their decisions with medical practitioners.
