Which items will I need to give my baby a bath?

Bathntime. Warm water and a very mild soap that you can use for the body and the hair make sure that the baby is not allergic to the soap.
Tub, warm water... Infants should bathe in an infant tub or a toddler tub with infant insert (generally a mesh swing that fits inside the toddler tub). Use warm water (not hot!) and gently wash the infant with a soft washcloth. Use nonscented baby soap/shampoo. Work from cleanest to dirtiest body parts and after getting them all soapy use warm water to rinse them off. Immediately wrap in warm towel after bath.
