Perhaps the person you should really be looking to for support in this is your sub. Explain that as you developing your Dom side you need her support, and that does not include undermining your Dominance by being bratty. A sub has a responsibility in making the relationship work too.

I observe that Doms seem to be split into two camps, those who like to control a bratty sub, and those will not tolerate it. Having been firmly trained that topping from the bottom is a big no, I find it hard to understand, let alone accept. But that point aside it seems to me that your sub needs to show some maturity, and support you by not trying to top you whilst you are still a 'Dom in training'.
