Asha, in my opinion it really depends on the individual family and their culture and mores.

However, I believe most men stop doing such things when their children are old enough to notice the physical difference between genders and old enough to ask questions about it!

That means most men cover up by the time their daughters are about 8 or 9 years old (if not sooner).

If your husband is doing this in front of your daughter, I wouldn't get all bent out of shape in front of her. You don't want her thinking the human body is something to be ashamed of, after all. You might start encouraging her friends (and yours) to drop by without warning, though.

One or two times of being caught nearly in the altogether might put the kibosh on his behavior a lot faster than anything you could do or say!
