Re: When did you start teaching your kids about touching?
I started around 2.5 with DD. She and DS bathe together and she went through a phase of being fascinated with his penis. So I had to teach her that it's inappropriate for her to touch other people's private and for other people to touch hers. We talk about the difference between mommy/daddy or teacher (daycare) wiping her after using the toilet... etc.
She's 3.5 now and it's been a while too that I try to explain to her that she needs to touch herself alone in her bedroom for privacy. She doesn't fully understand but she's getting there.
