pls advise: child making money, how to work on tax

my child is writing a book, and I think it looks amazing and plan to help publish it. we will prob invest quite a bit on third party services, including proof-reading, formatting, graphic design etc. 

question:

1- the tax consequences: since i am including the as my "dependent", will the cost be deductible under me when we do tax return? 

2- do we need to provide "1099" to service contractors? say, I pay 300$ to some graphic designer? 

 

I am sure there are a lot of entrepreneurs here. pls advise if you can. Bless you all.
