social media announcement

Amber
So we are FINALLY getting around to doing around Facebook announcement and I have a unique situation. My oldest bonus daughter is in California. The youngest daughter lives with us. How can we include her in the announcement when she can't be in the photos? We sent her a big sister again shirt to tell her and I have photos of her wearing that. We are having a mini session on Friday evening after we confirm the gender but only the youngest will be there but I feel a little guilty doing photos without the oldest but she won't be visiting until the end of June. We are doing maternity photos when she's visiting for the summer so she will definitely be in those. Any suggestions? Is it okay to do the main announcement photo with her involved and then the gender reveal without her? I want to be fair and not look like I'm excluding her.
