Weekly bath sorted! We only give our kids a bath once a week in only water. It might sound a bit strange but it is actually better for their skin. We do clean the kids bottoms everyday and occasionally if they are very grubby from the sandpit etc. we give them a quick rinse in the shower. We live in an area with very hard water and still never had any problems with dry skin, so we also never had to use any creams or oils.
What does work on baby skin is putting breastmilk in the bath water. You will never feel softer skin.
