Kids with sharp tongue at very young age  

I say there's more blame on the parents. They are the ones who should be raising the child and telling them what is acceptable and what isn't. I've seen the same thing and its extremely disturbing. Go out into a public place and you see these young kids cursing the parents and anyone else just because they can. It's not only the cursing but the violent behavior that these young kids are doing that is distressing. I know a woman who allows her infants to hit her and push other kids down. One time, her daughter almost pushed another child down the stairs without any provocation. Instead of telling them to stop or that's not right, she just laughs as if its the cutest thing in the world.
