Single Member LLC paying minor child to help out with business

Hello,

I am a single member LLC (reported as disregarded entity) in the bookkeeping business and I started to train/hire my child whos 11 years old to help out.  How would I pay my child?  Can I just write him/her a check and do I need to report this with EDD even if no tax, medical, futa, etc. is due?  Could I just write him/her a check monthly for the service and just report in my LLC as outside labor in my LLC books.  Do I need to register with EDD and report that I paid my child?  What should I look out for?  I want to make sure I am doing this correctly.
