well, you think you can build up pressure to get her in the belt? why don't you focus this pressure on forcing her to use contraception? would be more constructive from my point of view.
and as i mentioned in another thread, involve her a little more in the decision, don't do it from the top down. just ask her under what conditions she would be willing to go along with your idea?
if she answers that, we can discuss it further, but so far i don't see how you could persuade your daughter to wear a belt
