At risk of sounding weird - I'm going out on a limb here.....

How old (if at all) should parents start covering up their 'private body parts' in front of their babies / toddlers / kids....

Just recently I've overheard a conversation where a mother mentioned her daughter is 7 and her DH will still walk through the house naked in the morning / evening. Her friend said 'ewww, 7 is way too old' - as they stopped strutting around naked when their daughter was 3 -4....

So I thought i would ask you ladies out there....what do you think, and why??
