I just wanted to say welcome to YT and that your little one in your avatar is a sweetie pie.
I don't have experience with breeding and I do hope you hang around and browse the libraries and breeding section.
I would like to say that even though I'm not well versed in breeding, I have read that it is highly recommended to wait until 18 months to 2 years of age to breed a female. Just for her health. I know they have more than 2 heats by then, but I think for safety's sake, it'd be best to wait til she gets a bit older.
Look forward to getting to know you and your girl. What is her name?
