Hi! Therapist here- I love that you are asking this question because I bet there are other moms out there with similar questions. This topic can be uncomfortable to talk about but here are some tips:
- developmentally, this is VERY normal
- at this age, kids are just doing these behaviors because it feels “good” or “weird” (they aren’t sexualizing it- it’s just pleasure and curiosity)
- maybe next time she is doing it in the privacy of your hot tub at home, you can have a casual non-shaming conversation with her
- Ex: “Our bodies are really cool and they feel lots of different sensations! It can be fun to explore and be curious about the different parts of our bodies and what they do. Sometimes when we touch our private parts (or you can use the actual private part name) it feels good and that’s totally normal! But it’s something we do in private and not in front of other people. Just like when we go to the bathroom, change clothes, shower, bathe, etc...
- and make sure to let her know she can always come to you and ask anything on this topic in the future
You got this!
