Zero. I never wanted children and that has not changed. I'd be surprised if it does change.
I'm not ready to permanently say goodbye to peace and quiet. Toddlers, babies, little kids are dreadful, and to take care of one isn't something I want to do, although at least when they get older you can have a conversation with them, and under the right circumstances that might be worth it (a preppy daughter would be nice to raise), but I have no desire to take the chance.
That's exactly how I've always felt.
I always figured that if I ever were to have a child, I'd prefer it be a girl, and hopefully an adopted one at that. However, I really have no interest in taking that up.
