i remember seeing both mum and dad naked as a child obviously once i got to a certain age it stopped too. my kids see me naked a lot more than they see DH seeing DH would be when he goes to the toilet (DD2 is toilet training and fasinated by how differently daddy wees!) and when hes in the bath or shower or in winter getting dressed in front of the fire whereas with me they follow me everywhere so most likely whenever im naked they will see it!
