is there an unspoken rule with half siblings on pictures? We're having a girl and my boyfriend has a 4 year old daughter. I want some newborn pictures taken with her sister but I also don't want to upset her mom. The mom cried when she found out we were having a girl because their daughter won't be "daddy's only baby girl anymore." Also, his daughter is ecstatic about having a little sister, she s always coming up with different names and telling us what they are going to do when she stays the night like pint nails and play babies. She's not upset at all.
Re: half siblings/pictures
Regarding newborn pictures, my suggestion would be to feel free to take pictures of just the baby, but when taking family pictures, include the whole family - including big sister.
This is just to share my opinion based on my own experience. Good luck, and as long as there's lots of love to go around, you'll be fine
My stepson is 9, his mom are I were pregnant at the same time, she just delivered a few weeks ago. So he's going from 0 to 2 siblings in a few months time. I definitely plan to take newborn photos and include him too. I think it's important to be as inclusive as possible and to try and have a smooth transition. Even in the best situations, it can be hard with step parenting and "half siblings" and such.
Regarding your boyfriends ex, I wouldn't worry. Try to talk it out if you can, but overall just focus on your new family unit. I'm not sure how long you've been with your boyfriend or the current dynamic, but his ex shouldn't have any affect or input on your new family. Enjoy your sweet newborn photos!
Anyways, I would approach the mom of the daughter and talk to her about how excited you are for your little one to 'join the family' and let it be known that the family includes both her and her daughter. When you take your pictures - it sounds like you are having them professionally done so its not like you or boyfriend would be stuck behind the camera - ask to have the 'girls' in a photo by themselves, and maybe one of you and her with the girls, maybe one of daddy with his girls, and at least one where EVERYBODY is in it (you, bf, both girls, and the other mom). Including her into the family unit would not only be kind, I think, but pave the way for easy relationships going forward.
Good luck!

The extended family (my parents) are not always as accommodating to the "wait to celebrate" requests, but we all do the best we can.
Again, not saying this is the right or best way, just our way, since you asked. Modern families have their challenges and as @mellymar said, I think titles are either irrelevant or will reflect a relationship built over time.
Oh, I should add: my older (step-)niece's biological father is very much in the picture. He lives out of state but stays with them often, to visit and see school plays, etc. He is not included in any formal family photos - only my brother, his wife, and the two girls. Every summer, this niece and her father have their own portraits done together, alone. It seems to work, and she seems to enjoy having two dads.
