Babies (especially newborns) have extremely sensitive skin, and it can be difficult to get their bath temperature just right, because what feels comfortable to us may not always be comfortable for them. You can prevent unnecessary bathtime discomfort with Munchkin's White Hot® Ducky, a new take on the classic rubber duck. This hard-working bath toy has innovative White Hot® technology that warns you when bath water is not suitable for baby's delicate skin. Simply place the duck in the tub, then lift up to check the blue disc on the bottom. If it says HOT, add cool water or let the bath cool down before placing baby inside. Aside from being a bath safety must, this cute yellow duck is also water-tight, mildew-resistant, and fun for baby to play with. White Hot® Safety Disc reveals the word HOT in white when bath water is too hot for baby (104 degrees Fahrenheit and above) Fun, easy-to-grasp size and shape Water-tight to prevent sinking, squirting, and mildew Floats and makes a great bath toy Ages 0+ months
