I hate my photo being taken, DH hates his photo being taken, there are very few photos of me or DH with the children and my family hates it but its stiff biccies.
If one of my children turn out the same then so be it.
My desire for a photograph is less important than their desire to not be photographed, despite my cruddy memory, I have every day with them and even if I don't, I know how I feel about them, I don't need a photo to remember the things that are so ingrained in me, my personality, the way sleeping without my babies feels so weird and the feeling when I have them right next to me.
I have no right to anybodies image.
As for them feeling unloved later because there are no photos of them, photos do not prove love and she will remember how she decided not to have photos. In fact, I suspect she will remember more love because you decided to respect her wishes rather than the displeasure at being pressured to be in a photo.
If it is about control as you say it is, then I would suggest you find out why she feels she needs this control, it seems to be a much better way of approaching the situation rather than forcing her.
ETA: Also, for those who think you should just force her and/or that if she turned round when she is older and wanted nothing to do with you because if your lack of respect for her body.......... I was forced to dress up for photos and to have photos and I despised it, absolutely despised it and guess what, out of all of them I only have a kinda ok relationship with 2 of them (my step mum and dad) because they finally decided to just let go and respect me for WHO I AM (kinda, I still get crap for vegetarianism).
To my gran, I said in the end at the age of 23 (finally) 'I AM NOT your doll to dress up and do with as you please, I am a PERSON'.
I said the same thing to my mum. My mum cont being an a hole about it and we no longer speak, in fact I have no contact with that side of the family.
My gran at least kinda stopped and we kinda kept on good terms til she died.
I have zillions of photos of my kids but I filter through them all really carefully until I find the really good ones and only those will do and they have to be good.
I send family photos of my girls but it is on the understanding that the photos are for them only, I don't mind them showing the odd the person but I do not want what happened to me, happening to my children, I was treated as a thing and being pretty (which I supposedly was back then, long legged, blonde, blue eyed, athletic) made it ten times worse 'but your so pretyy', so what, because I am pretty I should just like to be photographed????????? What you look like shouldn't matter, its your feelings that count.
I have no photos of my dead brother, don't need them, in fact, we don't have any photos of any of my family, we don't need them.
My step son despises his photo being taken, he will on occasion allow it (he is 13 BTW) and it doesn't bother me because is his right to not want photos. It might be nice to have photos of him with the girls but it is not essential.
In fact, thinking about it, DH, DSS and I are very much into photography, we prefer to be on the other end side of the camera.
