How do I get started as a caregiver?

Margarita, you start with some training and many agencies will train you if you are working for them. I could give more info if I knew where you are. Many programs are funded by federal grants.

Are you a caregiver for an elderly parent?
Will you be living with the person you are caring for?
Will the person you are caring for be living with you?
What illnesses does this person have?
Is this person mobile?

I don't think this question can be answered without a little more information.
