This happened a few weeks ago and the restroom post made me think.
My son is 8 and goes into the change room with me at the pool. My husband is deployed and I have a lot of anxiety and stress, as well as not feeling comfortable with him being alone in there. There are lots of stalls with doors so most people are not changing in the open.
My son was dressed and ready to go, sitting down, while I was finishing up. A girl who was probably about 20 was changing a few feet away and was fully naked. Most women are more discrete, with towels, so he was a bit surprised. He turned and loudly whispered "Mom, she's NAKED" to me and giggled.
The girl turned around and said "What's your problem? I don't appreciate you laughing at me, and you shouldn't even be in here in the first place!" to him, while she shot him a dirty look.
As a mom, what would you have done?
