A baby is considered to be a newborn baby from the ages of birth until 2 months of age.
After 2 months of age baby is no longer considered to be a newborn and is now just considered a baby or infant.
Infants are considered to be infants from anywhere from birth to 1 year old.
The term baby can be used to refer to any child from birth to age 4 years old, thus encompassing newborns, infants, and toddlers
Newborn babies only need to be bathed every few days or so.
Wiping the newborn down with a wet washcloth is good enough most days unless the newborn has a poop explosion or diarrhea then it would be good to bathe them more often if that is occurring.
However you don't want to bathe the newborn too often as it dries out the newborns skin.
Babies only really need a bath every 2 to 3 days until they are a year old or older.
So a newborn can be bathed every 2 or 3 days but if the newborn needs a bath more often than that you can give the newborn daily baths.
When your baby is first born and you bring the newborn home from the hospital you should wait at least 24 hours after bringing the baby home to give them a bath.
Unless the baby happens to poop on their clothes etc and gets poop or vomit all over them then just simply wiping them down with wet wash cloths etc is usually good enough to keep the newborn baby clean enough.
But if you want to or need to bathe your baby once per day that is okay.
But as long as you're bathing your newborn every 3 days that is also good enough.
