Hi there this is Dr.Jody Navitsky and I can help you.
I apologize that no one was on line to answer for you when you asked initially but if you are still interested we can work together.
Let me know by replying and we can connect when you are ready. A few thoughts until then, squirming is most likely from itching/irritation vs pain. When they have pain or burning little girls will be more likely to cry than to writhe around. I would ask you exactly where she say it is bothering her, in her vaginal area, or on her bottom?
Any redness, discharge, anything that you see on the outside? Any changes in the way she poops especially a history of hard stools?
What about her urine? Spending a lot of time in the pool lately?
I will be on the lookout for a reply thanks!
