Not really lets say shes sitting on the sofa and just gets randomly aroused just see what she does if shes watching or reading something on her phone or tablet that is making her aroused she may have a play if she does then allow her to and if it goes to her taking off her pants and underwear and masturbating to orgasm be it just an orgasm or squirting or both just allow her to do so she may have questions if she hasn't squirted before as you haven't said but just let it happen and see what happens.
As a Mother with 2 daughters, 9 and 12, I'm glad I found this thread. I spoke to my husband about this, and he sees it himself too, and we thought about taking the kids to therapy at one point. We try to be as nice and clean as possible, and tell them that it's normal to have these feelings, and tell them that when they feel like it's their happy time, to go to their rooms and relieve themselves, but don't feel embarrassed when your around us. My husband is terrified and barley mentions anything to them. Same during COVID/lockdown when our 12 yr old was around 9-10, she would love to play with herself as she jumped up and down on her Dad. And now with our 9 yr old, she has the same tendencies, she especially touchy feely when in the pool. I don't want to get too graphic, but I'm happy to see that it's not so uncommon and more openly discussed.
I had a very similar situation to you we have two daughter 12 and 15 and they both started noticing it feels very nice to touch down there every once in a while we noticed the younger one going at it on the sofa we left her but I'm now thinking I should bring up squirting with her just in case there's a flood when she has an orgasm or before or even after one.
