My son will be 4 next month. I've noticed him asking girls his age and young adult women to take their clothes off. My husband and I have been racking our brains to think where he could have heard this. I don't think he's seen anything on tv or heard my husband say something like this to me. He thinks its funny even though I've explained to him that getting undressed is a private thing and to not ask people to do this. Where could he have gotten this from and how do I get him to stop?!
