You should bathe each and every day.
This depends entirely on how dirty the person is, and doesn't really have anything to do with age. A person should bathe at least every other day. If they are very active and sweaty, then they should bathe at least daily.
You can bathe your baby as many times as you wish. However, I would recommend that if you are bathing your baby once or more a day that you don't use any soaps or other bath products as it may dry out your babys skin and irritate them.
Two times a day.
two to three times a day
