I've always gone on the basis that as soon as your child feels uncomfortable around you being naked, you should start covering up/ closing the door when dressing or bathing. Ds is 9 and not remotely bothered but I'm starting to wonder if this is weird/ out of step with others. We don't parade around naked for no reason of course, but he will frequently see us naked getting dressed/ undressed morning/ night. How open are you with your kids and what age did that stop? I've seen some experts say that it may be inappropriate from 5 which has concerned me tbh.
