Also just wanted to add that if you are getting divorced, do whatever you can to push the proceedings along. In other words - get divorced asap. Otherwise, your child bfing will continue to be used as a tool. And a bfing 9month old is not looked down by the courts nearly as often as bfing a 20 month old, or a 30 month old, kwim? You don't want to be in the position of them forcing you to wean just so you can keep custody. Right now you have the AAP on your side. Once you get past a year, though, your support from teh legal system will all but vanish. If you divorce now, things will likely be set in stone for at least 2 yrs (for most states), giving your much more freedom to bf how you like.
Also, why are you holding out on giving her/him solids? Do you have a medical reason? Try to take this issue away from them. Say that you are offering solids. Find something to offer. You'll find a lot of support that the legal eagles will believe, in offering only one new food at a time. You could drag this out for a few months while you get the divorce through in the meantime. Allow others, like your husband, to offer certain solids. I know this is not what you want to hear, but I really think that damage control is the issue right now. Not vax'ing is a more difficult issue.
You are dealing with people (lawyers & judges) who are making a decision between two parents for what *they* think is better for a particular child. They are very likely not going to change their mind bcs you educated them in the courtroom setting.
Speaking from experience here, unfortunately. Think of what you are fighting for - not to change their mind or educate them, but to win the right to make these and other decisions for your child. Get that right legally asap, by getting divorced asap.
hth - I'm not trying to make problems, but to save yourself much, much grief over the next year.
