Anyone who has ever had to draw a bath for a baby, or just a young child knows what a guessing game the water temperature can be. Especially if you aren't used to doing it, or just have always taken such hot showers yourself that you can't really feel when the water is too hot for the younger ones.
This cute little thermometer floats in the tub letting you know if the water is entirely too hot. It would even blend in well with other bath toys floating about.
The cute little thermometer is made of soft plastic, so you won't have to worry about your little ones getting hurt with it. It is being sold for $12.
