Sounds exciting for a dad and daughter hobby. Congrats and I hope to follow in your footsteps when my kids are a little older and know what a computer is. I know many people give negative feedback on minergate, but I have only used that. Yet a lot of crytonote coins on minergate have now increase hash rates, almost 50% increase so I am assuming some of the nicehash users are moving over.

You can also start looking into bitcointalk.com where there is a ton of info regarding where to mine.
