Ideal Temp Feeding Spoons let parents and caregivers know when food is too hot. When the temperature of your baby's food is too hot (approximately 40 degrees Celsius or above), the thermometer-shaped area in the bowl of the spoon changes color. Soft spoon bowl is gentle on baby's gums while the extra-long handle provides a comfortable hold. Available in 2-pk or 4-pk. Recommended for ages 6+ Months. Top rack dishwasher safe.
