Once you've undressed your baby for the tub bath, place him in the water immediately so he doesn't become chilled. Use one of your hands to support the head and the other hand to guide him in, feet first. Talk gently to the baby and slowly lower the rest of his body until he's in the tub. Use a washcloth to wash his face and hair. After the bath, wrap your baby in a towel immediately, making sure his head is covered.
Baby towels with hoods are great for keeping a freshly washed baby warm.
While bathing your infant, never leave the baby alone. If you need to leave the bathroom, wrap the baby in a towel and take him with you. For specific medical advice, diagnoses, and treatment, consult your doctor.
