To ensure hygiene, clean thoroughly using mild washing up liquid and sterilise before every further use. Press out any residual liquid from the baglet after cleaning or sterilisation and let the soother dry afterwards. This is to ensure hygiene. Do not clean the soother in a dishwasher as detergents can damage the material. When using any steriliser or sterilising solution, please follow the manufacturer's directions to avoid material damage. Store hygienically in a dark place.For your child's safety - Warning!Never attach ribbons or cords to a soother, your child may be strangled by them. Inspect carefully before each use, especially when the child has teeth. Pull the soother in all directions. Throw away at the first sign of damage or weakness. Do not leave the soother in direct sunlight or near a source of heat, or in disinfectant (sterilising solution) for longer than recommended, as this may weaken the soother, In rare, individual cases, children manage to put the complete soother into the mouth. In such an event, Do not Panic! Due to its special design the soother cannot be swallowed and the two aspiration holes ensure sufficient breathing. Remove the soother from the child's mouth as gently as possible. Do not dip the soother into medicine or sweet substances and do not lick the soother. Both can cause caries (tooth decay) to your child. Replace the soother after 1-2 months use for reasons of safety and hygiene. Even without visible damage the stability of the soother may have been weakened.
