RE: taking youth, climber?
That will be solely up to you and your child.
Every child is different.
If your child agrees that he can do it, take him out and practicewith the climber only getting a few feet off the ground. Let him set the pace and height, you hunt according to his comfort.
However, I agree that a ladder stand for the child would be be a better choice. Two man ladder stand will give you complete control of what the child is doing.
