I think my wife is too obsessed with hygiene and is overprotective of our daughter. How do I tell her to be more carefree?

Its good to be clean... rather than dirty right? I understand being parent can be overprotective at times. This has to be in moderation, as too much protection will not prepare child to be independent. where hub and wife shld work hand in hand. In case one party overdo, just sit down and discuss abt it when child is not around
