Thermochromic heat sensing symbols on the bottle provide an indication of the milk’s temperature. A simple twist of the bottle base adjusts the heat, enabling full control of the temperature, so a warm feed can be safely delivered whilst on the go or in an emergency. Both teat and formula are kept separate in foil sealed sterile sections, permitting storage for up to 12 months. The Qi product range comes in a variety of formulas, flow rates and sizes for infants from 6 to 24 months.
