Ok, I'm doing pictures for my upcoming announcement, but I need to figure out how to incorporate a child that isn't allowed to see her father (His ex is very stubborn and we are trying to go through court but it is costly for us atm).

I have a boy and girl, he has the daughter, we are obviously having one together. Im using a white board and want to dress what we all want in corresponding colors and need something cute to say. I dont want anything too generic. I was thinking of a "tie breaker" something, but technically it's not a tie breaker if together we have the 2 girls and 1 boy. But his daughter sadly wont be in our pics😔 so I need ideas on what I can do to either incorporate her without her there or (for a serious lack of a better word) overlook the fact that she isn't in the picture at all yet. Makes me very sad that we are missing part of our family during this new addition😔, but what can I do?
