If you have small grandchildren children and don't have anti-scald devices on your faucets and shower heads, adjusting the thermostat on your heating to 120 degrees Farenheit can prevent accidental scalding burns.
When filling the bathtub for small children, hot water should never be run on its own. Always run the cool water before the hot, and turn off the hot water before the cool.
Never leave a child with a filling tub. When a child is present while you fill a tub, make sure they don't play with the faucets.
Always test the water yourself before placing a child in a bath tub.
