How often did you bathe your newborn? Do you need to wash their hair with shampoo at each bath time?

I bathe my baby once everyday and wipe down once at night. I don't wash their hair with shampoo. It is difficult to wash off the shampoo when they are still young and soft and besides they don't get dirty easily. I only press a pump of top to toe soap into the water and wipe their head with a washcloth several times making sure that it is thoroughly wet before drying off and continue to wash their body.
