Torn between my children

I am 40 & 18 weeks pregnant. I have two older daughters (23 and 20) from a previous marriage. Unfortunately they are not on talking terms. This breaks my heart. I feel guilty when I spend time with one and not the other. I wish I could spend time with them together. They just don’t see eye to eye on things right now. They’re two totally opposite personalities. I love them both so much. I feel that because I am torn between them two that my baby is feeling it too. I’m stressed and super emotional. The only thing that they do see eye to eye on is this baby girl growing inside of me. I just don’t know what to do anymore.
