Newborn cough

Hi my baby is 2 weeks old and he started a few days ago with a mild cough he usually coughs after he is fed which I'm thinking is normal but sometimes he just coughs when he isn't fed & im probably over thinking and worrying to much but is it normal? He doesn't have a temperature and he does sneeze but he has been ever since i gave birth & midwife told me its normal but I'm abit worried and don't know if I should go GP with my son, he doesn't cough all the time but the fact that he is coughing is stressing me out
