Here is a very helpful video on how to give baby baths. Give it a watch. They recommend that you put the baby bath on the kitchen counter because that is a comfortable height for average people. After you put the baby in the tub place a washcloth over the babies belly. Take special care to use the right amount of soap so you get the baby clean while at the same time not drying out their skin. They also suggest starting with the face because you want to do this while the water is the most clean. Work your way down the body and finish with the babies bottom. Assuming the bottom is the most dirty area of the baby. Shampoo is determined by the amount of hair the baby has.
