How to deal with this?

[Noodlesinthepocket]

New here, and a FTM 38 weeks gone.
Me and my sister have always been very, VERY close, she's even going to be one of my birthing partners on D-day.

We were talking a few days ago and she noted that a certain photographer was going to be around our area again, one who specialises in newborn photoshoots and can get them free etc.

Now, no offense to any of you who like these photoshoots/have had them/want them etc, but I can't stand them! I find them so cringey and I really don't want to get involved with them. I'd rather just take my crappy quality phone photos!

I told my sister this, and she just said "well okay I'll just take her for them on my own!"
I'm not one for confrontation but this idea makes me incredibly uncomfortable. I just DO NOT want my baby to be part of one of these shoots! The babbies always look so uncomfortable etc and I do just find them so cringeworthy. If she brings it up again, how would you go about telling her "no" without upsetting her?
I may not like confrontation but I can be very blunt which can upset people sometimes!

Is she really going to have the chance to take your newborn out without u? Take some pics and tell her she can buy some frames.

It's quite easy, you tell your sister that don't like them, don't want pictures like that and that she's not taking your newborn baby anywhere on her own. Job done.

If you're that close you should be able to say, "sorry but I'm not going to allow this". I would also use this as a practice example because it seems likely there may be other things you disagree on, and your sister sounds like she feels she can treat your baby as her own!!
