For me, it's just not appropriate content for kids that age. I'm assuming there must have been parental agreement in all of this, and for the life of me I do not understand why any parent would agree to have their child doing this. It's like these Beauty Pagents for kids in the US - I mean what's that all about?
Oh right... I was actually asking the question about children being like that in reality.
But in regards to the acting, well there isn't anything sexual, just innocent puppy love or whatever you call it. So I don't see a problem there.
The beauty pageant on the other hand is disgusting.
Kids enjoy copying adult behaviour, but do not have adult comprehension.
I do share that concern although what we saw in that video was not inappropriate, just shows a lack of innocence if connected to reality.
