The GAL is the legal representative of an interested party, i.e., the child, and not a neutral decisionmaker. The GAL has no authority to make orders, and to do so, without authority violates the GAL's professional duty to not coerce an outcome in his/her client's favor by unlawful means. I would complain to the court that the GAL is using improper methods to influence to course of litigation in matters that are for the court, and not the representative of an interested party, to decide.

No. In my opinion, you are voluntarily submitting to things to which you have no duty to submit. You may want to mention to the GAL that she needs to make the fact that she represents an interested party clear to an unrepresentated party, and that she should not be offering legal advice to an unrepresented party, other than to seek independent counsel, because to do so, is a violation of the Rules of Professional Conduct.
This will probably cause her to dirty her underwear, because you could make an ethics complaint and she could find herself suspended from practice for a while.
Now, having said all of the above, I must caution you to realize that the GAL can be your friend or your enemy, and the former is better than the latter. The question is whether or not the child's best interests are being served here or not, and I can't really determine this from the few facts you present.
