Is it safe to put videos of your child on youtube?

[lisa]

I want to make a youtube account with videos of my nephew singing, dancing etc like you see others doing. But when I told my sister she said make sure the name is not a real name (so I'll make up the name for google+?) and make sure it's private because it's not safe. People post videos on youtube of their kids all the time but is it really safe for the world to see? Because if I make it private then I don't even see the point of making the account since I can post videos on facebook for just friends to see. And another question I have is, is it possible to make all the things I share on google+ private?
