150ml bottle with silicone non-spill spout (replacement spouts available). Suitable for children from 6 months +. For safety and hygiene purposes we recommend that you replace spouts after 1-2 months of use or whenever they start to show signs of wear. Prior to sterilisation we recommend using the NUK Baby Bottle Cleanser, its natural formula removes dried on milk protein, pulp and juice residues more effectively than hot soapy water alone. To sterilise cups and spouts we recommend using steam, cold water sterilisation or a NUK Steam or Microwave Steriliser. We do not recommend dishwasher sterilisation as this can cause material damage.
