yes ok that's fine, all I'm asking here is how do I start I know it will take a lot of time maybe years but how do I become a children's performer?
The answers to that question are already in this thread. Reference material has been listed... general guidelines provided. Go back and copy them all down and go to it.
Here are a few more things to think about:
To become a children's entertainer, you have to do two things:
1) Become an entertainer, period.
2) Understand children.
You don't necessarily have to do them in that order, but you do have to do both.
Regardless of the type of children's entertainment you choose to do, whether it's magic or music or storytelling or balloon sculpture, you have to be very good at it. Master your craft.
Regardless of the audience you want to perform for, whether it's children or adults or teenagers or drunken Shriners, you have to fully understand your audience -- how to relate to them and how to most effectively perform your craft, whatever it may be, for that audience.
There you go. That's it. Easy to write... not easy to do. But if you do it right, you are almost certain to do it well.
If you don't do it right, you will humiliate yourself, disappoint the kids, anger the client, and put another nail in the coffin of children's magic.
It's easier and more comforting to be hugged by amateurs than to be disciplined by professionals, but one will get you work and the other won't. It's all up to you.
