For parents who just have a baby, it is an important thing to have a good command of feeding with bottles. However, some careless parents might forget to test the water. Besides, some bottles are so thick that parents
can not judge the exact temperature by feeling, which might hurt the babies. Baby Guardian can well solve this problem. We use the principle of thermal expansion and contraction. When the temperature is above 40 degree Celsius, the nipple will shrink for stopping the milk flowing out. And only the temperature is at a proper point can
the feeding bottle be used normally.All in all, Baby Guardian provides protection for babies.
