when do I give my baby a bath or wash her?

Whenever you want. Every 2-3 days.

she is 5 days old. and how do I bath her?

when the cord is off or just be careful and keep it dry

its best to wait when the cord falls off before you bathe her in a tub. until then its best to just wipe her down real good with a washcloth

thank you all so much
