Make sure your baby’s bathwater is comfortable for him using this Baby Bath Temperature Thermometer Duck Toy! It is convenient to use! This is a digital thermometer so it is easy to read. You can change the units and it has a built-battery already too. The color of the screen turns green when the temperature is just right, red when it’s too hot, and blue when it’s too cold. It comes in the form of a floating duck toy so kids can also play with it.
