Nuk First Choice+ Temperature Control Bootle indicator gives the assurance that the contents of the bottle are not being fed too hot.
It looks like a thermometer, is located within the graduation marks and the temperature of the contents of the bottle makes it change colour. The normally blue indicator will turn white.
The special Nuk shape is modelled on a mothers nipple as she breastfeeds. It leaves your babys tongue and jaw enough room for natural sucking movements.
The Nuk Anti-Colic Air System ensures a natural flow to help your baby drink without swallowing air.
