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

I had the same problem with my husband. He's been over protective with our son. He does let him be active. I did not want my son to get hurt, yet i don't want him to be lame either. When I try to talk to him it's like I am the one who doesn't care about my son's safety. I know where you're coming from.
