Some families, and indeed, some cultures never have this kind of thing come up.

It is a matter of personal morality. If there is no problem with the parties involved, then why make an issue of it? Now, myself, I am never nude around children. But it is my decision on that, and I am not about to judge others who may have less modesty than me.

For a general opinion.. I's say when the boy starts making faces like this..

It may need to stop...

Hmm... well... when I was six, what bothered me about naked adults was the pubic hair.

I'd done plenty enough playing doctor with other kids in the neighborhood to know what naked male and female bodies looked like, plus I had three sibs, two brothers and a sister, and we took baths together all the time, so that wasn't the issue...

The problem was that pubic hair. Yuck.

Maybe it wouldn't be so bad these days, because these days people tend to trim their pubic hair like they tend to have tattoos, but I thought it was gross, and I didn't get over it until the hormones kicked in.

When it comes to nudity, there's the modesty aspect, and then there's the decency aspect, and when I was a kid, I definitely figured it was more decent for adults to at least wear a thong.

My answer would be a FIRM NO.
You may think that it's okay for a 6 year old to see his/her father's girlfriend naked, because they are still young.

Well, from experience, I have a neighbor who has a 5 year old son and at a young age seem to know a lot of "stuff" that he keeps asking me. I reckon he got that from his parents? I find it annoying because he is a kid, and he doesn't know that he is OFFENDING me or other people.

for example, he slaps people's butts or poking them. pretty annoying for a little kid!!!!!!!!!
I can't do anything either because he's a kid.

It really seems wrong to me because for me, what Hilary Swank and his father has should be between them. They don't need to show her body to her boyfriend's son! I find it really annoying. From my example, even from a 5 year old.............I don't think it's "acceptable".

This might have a psychological impact on the kid, (even when he grows up)
but that's just my opinion.

what do you think?

I think under no circumstances should she let another person’s child see her naked, unless of course the encounter is due to accident, such as if she forgot to bring a towel into the bathroom and tried to make a dash for it but the child ends up spotting her. However, it is not okay to make a habit of letting the child see her naked. First, of all since she is not his parent, the child is likely already undergoing adjustment issues to adapt to the new situation of his dad having a girlfriend. Seeing her naked will only further complicate his feelings and add to his confusion, since he is likely not yet familiar at such a tender age of why adults are laying naked together. This encounter may just further invade the little boy’s personal space and make him realize that he now has to share his dad with somebody else in a way that he is never able to measure up to (no matter what your age, you will realize that nakedness is associated with a level of intimacy that is not common among random strangers or friendly relationships). Seeing a naked person may also scare the little boy and feel ashamed for that person. It’s a confusion and inappropriate message to send a child. Even parents should not parade around naked in each other’s presence when their children have easy access to the room. There’s reason why adult relationships are kept private. Children’s eyes are just not meant to witness such incidents yet.

Depends. Is father's girlfriend living with them? Will father's girlfriend be stepmom, or already acting as stepmom?

My son 'sees' me naked all the time. I have health issues, and sometimes, on the bad days when I'm mostly wheelchair bound, he helps me shower even. He's a good kid like that. On a good day, I'm just as normal as anyone else though.

I've never been 'ashamed' or taught my kids shame about nakedness. Nudity isn't shameful. There is a difference between shame and modesty.

I don't flaunt being naked in front of my son, but I also don't freak out and make a huge deal out of it when he does have to see me naked. I sleep in the nude, and it's not unusual for my son to come in to the bedroom in the morning and sit on the edge of the bed and chat with me. He 'knows' I'm naked, but it's not like I'm being sexual of even exposed to him. I'm in bed, under the covers. I lay there with my husband, who might or might not be naked. That's a normal, healthy relationship and sex is a part of it and sex is not shameful. Doesn't mean I'm going to have sex in front of my child, never, but it also means I don't try to hide the fact that sex is a normal part of a relationship. One day, my son will grow up and have a sexual relationship in his marriage, and I hope he can feel as healthy and relaxed about it as I do with my husband and my husband does with me.

That said, Ryan is not my son's father. My son was 13 when we got together, and he's 15 now. So my son was older and Ryan didn't come as part of the family from birth. Because of this, Ryan is much more discrete. He takes care to be modest and not expose himself around my son--but again, there's no shame when, living in a household with a bunch of people, someone walks in while you're changing of you forget to lock the door when taking a shower.

I think shame can be taught. I think modesty can be taught. How we handle things like being naked with our children helps shape their own self image and confidence.

All that said, I would NEVER bring a man around my kids to spend the night in the home my children wake up in unless that man is going to be a permanent fixture in my and my children's lives. I don't think it's appropriate for a parent to parade their boyfriends or girlfriends in front of their young kids, naked or not.

Lastly, things in the media are frequently taken out of context and misconstrued.

NO!!!

Yes. Apparently she is not particularly a nudist but she likes to sleep in the nude and the kid likes to come into their room in the morning. This is what she says:

"“I don’t sleep in anything, but my boyfriend’s son is six years old, and you wonder at what age you should stop walking around nude. Every morning he comes into the bedroom, and you’re just nude. But he doesn’t look twice – he doesn’t think about it yet,” Contactmusic quoted her as telling America’s Marie Claire magazine."

This seems entirely natural and normal. It would be interesting to see some actual studies of what ages in what cultures one needs to avoid nudity. Since people were invented before clothes it seems unlikely that there is ever any harm to it. For hundreds of thousands of years no one wore anything, so there can't be any drastic disadvantage.
So I'd say she doesn't have to start covering up at all.

I honestly don't see the problem, but I guess it just depends on what you believe. I'm sure you saw your parents naked before, or your mother at least.
