My friends 7 year old humps things

I actually learned in a health class once that masturbation, in this sense grinding on soft toys, blankets, etc., amongst kids is quite common at about that age. Its not really of any concern, they typically don't know what it is they're doing and is just a comforting experience to them. Its natural. Also worth noting that this sort of behaviour is typically NOT indicative of sexual abuse. If it were occurring they would most likely not want to explore that area.

I think it's fairly normal in and of itself, but more "curious" children are naturally easier targets of sexual abuse; that said, I do suggest you speak about this to someone - and to only her if to no one else.

Its normal, very normal actually. As i started humping the floor and my bed when i was around 2-3yrs old. My oldest stepsister humped her bed pillow and teddy bears. As well as her daughter which is my niece. When she turned 7yo, she would hump the floor not even 5 feet away from me. Staring me in my eyes while she pleasures herself. Watching her eyes almost roll in the back of her head moaning breathing hard. Staring at me the entire time shes pleasuring herself not removing her eyes from me until she was completely finised masturbating.

She probably accidentally discovered it. I accidentally discovered it when I was 7. I was pressurizing a water gun during the summer. I couldn't pump it fast enough with my 2 hands. My friends kept getting me. I came up with the Idea to put it in between my legs and sit and use both hands to pump it up. And you can really guess the rest. I didn't know what it was at the time (I made the connection at age 9 or 10). My guess is that the girl has no idea what it means. I'm no parent, but I think it's nothing to worry about.

Not having ever being a little girl, I'm not too sure how common this is, but my second wife said she found out it was quite pleasurable to touch herself at about that age. Fortunately, her parents were intelligent individuals and didn't make a big thing of it and didn't make it a "bad" thing, if they even knew (I'm sure they must have).
It's a very slippery slope, to determine if it's because of abuse or just a natural course of self exploration, but making it a "bad" thing can irreparably destructive, I believe.
I'd be extremely cautious on this and perhaps a few girls will step up and give us some honest and useful suggestions.

It's normal for children to be curious. But it seems as if she saw something and is copying it. I'd just bring it up to the parents.

I would be concerned about exactly where/how she learned this behaviour. Something inappropriate and suspicious seems to be occur. Talk to her mother. Alternatively, you could also consult a child therapist specialising in sexual abuse, on how you should approach this situation.

I strongly agree you should tell the parents because every parents deserves to know what's going on with thier child. And me being a rape victim my urge to explore became greater somehow but then again it can be nothing everyone goes throught so YES tell the parents you'd be doing the right thing

I was 6 when it started I can't remember how I learned (or if someone taught me?) I was caught doing it in my room with a life size doll I had a bad feeling like I knew it was bad I can't remember any thing about learning it I still do it to this day (13 years old) I know what it means no one eles knows that I do it what do I do do I need help ??

It can be normal, as a young child I often grinded stuff and often had an orgasm although I have discovered (after having my own children) it's more common in girls as they are more curious

Yeah I agree frickin weird and mother dearest does know what brat is doing. Mayb momma and pops need shut the door to the bedroom or tell kiddy poo she needs go damn room

Yeah, I'd just tell the parents about this sort of thing, if nothing else it will open up the door for them to talk to her about it. It could be a warning sign of abuse, it could just be her being curious. Do not talk to the child directly about it, you don't want anyone to get the wrong impression and it will look very incriminating against you to talk to someone else's child about sex.

this is kinda normal for that age really. they're starting to realize that it feels good to touch themselves, but they don't yet understand when it is and isn't appropriate.

it's ok to tell her mom so her mom can handle giving her "the talk" as she sees fit

I think it could be normal because maybe she has seen her parents going at it

Actually, it's not as weird as you think it is. its generally around that age that (as someone mentioned before) we realise that it sometimes feels good. And of course we're not taught to be ashamed of that behaviour or to reign it in until later, so we don't realise what we're doing is considered weird.
In regards to this girl she does sound a bit over zealous :p Maybe she's copying something she saw on TV?

I think she may have caught her parents at it, or seen it in a movie and is now acting it out with no clue as to what it really is, when I was seven me and my friends used to act out things on tv all the time, its how kids learn, this is just a example of how hat sometimes goes haywire

She only seven yrs old come on . And if she is getting abused if I was momma I throw person in zoo with bunch horny gorillas and watch them get raped in ass ha ha ha see they like it being raped in ass by fricken monkey they never be the same again but feel just like the girl

kids do weird stuff all the time i hate kids so much
