Tsvesta-- I think letting the breeder keep Kaya for a month would be your last resort. I know how you feel about doing exactly as what dad says. I have a strict one as well
Have this in writing and make sure you'll be getting Kaya after a month. This way, you'll be able to avoid any discussion from your dad and all would be fine. And I couldn't stress this enough--have this in writing with the breeder. We know you've been excited about getting Kaya and taking care of her. Just think of it this way, you'll have another month to prepare and anticipate her arrival. You'll have everything ready and you'll be the prepared super mommy that you are!! Hope everything works out well.
