Essential steps include:

• Undress him, dip his feet in the water, and then lay him in the sponge insert. Hold his head up with one hand while you wash with the other.  The water should be deep enough to keep him warm, but not so deep that he will start floating and become difficult to hold onto.
• Using a soft washcloth and a small amount of baby soap, bathe him from the feet up.
• Dip the washcloth in the warm water repeatedly and let it flow over him to keep him warm. 
• Be careful to not get soap in his eyes; wipe them from the inside out after you squeeze excess soapy water out of the washcloth.
• Do his scalp last, and using the cup, make sure the water flows off the back of his head and does not get in his eyes.
• Rinse him off with cups of warm water, then carefully lift your slippery baby out of the tub, bundle him in a towel to dry, and diaper and dress him.  

Enjoy the moment and then show mom her happy, clean, sweet smelling baby.
