Is it normal for toddler girls to grind t

My 2yr old daughter occasionally grinds her vagina against different things, sometimes a ride-on toy, on the floor, her car seat belt buckle, edge of a chair, anything with a hard surface & even rubs/pats with her hands when she can. We have ruled out the possibility of it being a UTI (Urinary Tract Infection) & she has no questionable discharge. When we notice this we check her nappy/knickers to see if maybe she is experiencing some irritation from urine or a bowel movement yet she is always dry & there appears to be nothing in her vagina. Does anybody know why she is doing this? Is this normal?

Sorry odd question but i am not sure if i should be worried or if its just her exploring her body. She will often fall a sleep in this position. I have spoken to a couple of doctors about it but neither of them really helped. One said that it was odd behaviour and the other said some kids masterbate.

Help....

yea i would not worry about it! i heard of a girl just like that and she use to sit in her carseat and constantly rub agaisnt the middle part , id say shes just exploring her body and well hey it might feel good which is why she keeps doing it , only thing i can suggest is maybe as she gets older explain that thats the sort of thing we do alone in our bedroom lol .

One of my twins does it all the time. Plus two of my sisters daughters did it as toddlers as well. They just discover one day that it feels good and they don't understand that they shouldn't in public lol. If Hazel does it I just tell her that if she wants to do that to go to her room and that it's not nice to do it in front of other people.
