My nearly 4 year od had suddenly become extremely modest and I'm not sure if this is a natural part of her growing up or if I should be concerned she's picked this attitude up from someone. Our family has always been really comfortable with nudity. There's never any comments like don't come in here I'm changing, and she sees us naked all the time and has never had a problem with that. However recently she has started saying she doesn't like to change in front of others, like in the locker room at the pool or when she is playing dress up with her female friends. We had a long conversation yesterday about how she doesn't like it if her friend comes into the room while she's changing and what she can do to keep it from happening. On one hand I'm pleased that she is aware to some degree that it is not right for any random person to see her naked, but on the other hand I don't want her to get the idea that her body is a shameful thing. Any good tips on how to address this without totally confusing or overwhelming her? She did mention in our convo yesterday that she doesn't mind Mommy, daddy or baby sis seeing her naked nor does she mind seeing us naked, so at least she's comfortable in that area.
