Included in the Starter set are some essential items to feed, prepare and sterilise food for the baby. Set includes NUK First Choice Temperature Control Bottles. The NUK orthodontic teat is modeled on a mother's nipple as she breastfeeds and is designed for babies that are bottle and breastfed. Babies can enjoy an even flow without swallowing air thanks to the NUK Anti-Colic Air System and parents can enjoy the extra reassurance that the milk is at the right temperature thanks to the NUK Temperature Control indicator. It looks like a thermometer is located within the graduation marks of the bottle, and changes colour if the milk is too hot. If the food is too hot, the normally blue indicator will turn white. To help warm up baby food very quickly, it comes with a Thermo Express Bottle Warmer which uses steam and just takes 90 seconds. Also included is an elegant and user-friendly Express Steam Sterilizer which can steriliser 6 bottles and accessories within 6 minutes.
