Before first use, and periodically thereafter, ensure to sterilise your MAM Original Soothers. The included travel case allows for convenient self-sterilisation: add 25ml of water to the case, place the soothers inside, close the lid, and microwave for 3 minutes (check microwave wattage for precise timing). Always allow to cool before giving to baby and drain any remaining water. These soothers are generally compatible with standard baby soother straps. For daily care, wash the soothers thoroughly with warm water and mild soap after each use, rinsing well. Do not use abrasive cleaning agents. Inspect the soother regularly for any signs of damage or wear; if any are found, discontinue use and replace immediately. Store in a clean, dry container when not in use.
