The dummy shield has a curved shape at the top, which provides plenty of room for the tip of the baby's nose. The dummy also has ventilation holes that provide air around the baby's mouth. It has a solid safety ring so that it can be attached to a dummy chain. Remember to boil the soother before use to disinfect it and then do this regularly. The dummy head can become fragile over time, so check the dummy and replace it if it is worn or cracked.
