These MAM Night Soothers are specifically designed for infants aged `0-6 months`. Always ensure you are using the correct size soother for your baby's age and developmental stage to support healthy oral development and safety. There is no complex 'setup' required; simply remove from packaging, inspect for damage, and sterilise before first use. Compatibility is universal with any microwave for sterilisation. To care for your soothers: 1. Initial Sterilisation: Before first use and regularly thereafter, sterilise the soothers. Place them in the `self-sterilising travel case` with 25ml of water, close the case, and microwave for 3 minutes at 750-1000 watts. Ensure all water has evaporated before use. 2. Daily Cleaning: Wash thoroughly with warm water and mild detergent after each use. Rinse well. Do not use abrasive cleaning agents or anti-bacterial cleaners. 3. Inspection: Regularly inspect the soother, especially the teat, for any signs of wear, tears, stickiness, or damage. Replace immediately if any damage is found. 4. Storage: Store in a dry, covered container. Keep away from direct sunlight or heat. 5. Glow Activation: To maximize the glow feature, expose the soother's button to light (natural or artificial) before bed. The brighter and longer the exposure, the brighter and longer it will glow.
