Og, my heart goes out to you!!!
I have three sons. The two oldest were baptized when they were 10 and 11. (Way too young!) I was DF'd two years ago, when my youngest was 9. He was wanting to be baptized at that time as well. Of course, I was against it, but his father was encouraging him. I told my son it was ultimately his decision and I would love him and support him no matter what he did. However, I did have what I was going through and the shunning and rejection from our "friends" to kind of point out to him. So I said, "Do you see what a big decision..life decision, baptism is? Should you ever "sin" or have a change of heart as to the beliefs for ANY reason, this (being disfellowshipped and rejected and shunned by all) is the outcome. You might want to think about waiting until the next assembly (this way it didn't seem like too far off, but yet it was enough for him to do some thinking) and then see if you still feel baptism is something you want to do. Well, as time passed, his heart went out to me and saw how unloving JWs can be when you do not follow all their "rules." Today, my two oldest (teenagers) have stopped going and tell me how happy they are to be out and to have a chance at life. My oldest has started college and has great potential for making a very happy life and career. The two that were baptized told me they did it at the time because "everyone wanted them too" and they wanted to "do the mikes." At 10, 11, 12, 13 etc. do they REALLY know what they want? I know at 14 I got baptized only to please my dad.
My advice is, find out WHY SHE wants to get baptized? Then if it is a legitimate reason, then tell her you love her and you'll always be her father and there for her no matter what she chooses in life. I promise you this will weigh more with her than anything else you could say.
I wish you the best and keep me posted as to how the two of you are doing.
