The childs dummy is designed so as to have a replaceable dummy part, which can be exchanged according to the requirements of the purchaser. The replaceable dummy part can be filled with different fillings if required. Fennel can be used for calming the child and/or caraway seeds for treating wind. Fluorine can be used to protect the teeth. Instead of taking tablets, the chemist could supply medicine in the dummy. If required the dummy can be used with no filling.
