How do you wash a baby?

you have a delicate sponge (a big one) and about 20cm of warm water and a sea sponge you buy in a baby shop so you undress your baby then carefully with a hand under the head put your baby in the bath on the sponge if its newborn just carefully dab the baby with the sea sponge and if its a little older get sensitive baby wash and dont get it in the eyes :)
