DH and I will meet his 15 year old biological son for the first time on Saturday. It was a one night stand situation. When SS was born, BM and DH agreed that DH would carry on with his life and they would carry on with theirs. It was like signing over his rights, only he didn't. He has paid child support all 15 years. SS had another father, but doesn't now. We've recently been in contact and SS, DH, and I are planning to meet for the first time. We have other children. Our DS18 knows about the situation, but DD11, DD6, and DD5 do not. I need advice on how to tell the girls. I also need advice on how to act and what to say during the meeting. It's exciting for us all, but a little nerve racking.
