Hi! I will be starting my nursery/NICU rotation and I am thinking on whether I'm going to need a new stethoscope for this. I already own an ADC 608, which has a pediatric diaphragm, but I think it might be too big for the IUGR and preterm newborns. Budget is also something I have to consider but I don't want something that's too bad quality only to try to save some money. Is it a good idea to buy one? If so, I am between buying an ADC 605 or maybe a second hand Littmann Classic II Infant. Any advice would be appreciated. Thank you.
