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 105 degrees F 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.
