The Big debating question

Well over the months of being pregnant we have contatplated going to our 20 week appt. by ourselves or having my mom come with us. This is the day that we will find out what we are having. Since we found out we were expecting we had decided that it just be us two and we were ok with that. Well as time has gone by we began thinking of how to tell the family what we were having, I did not want to just call them over the phone and tell we having a boy/girl. After much debate we had decided to tell them Christmas Eve since our appt. is only 8 days from Christmas Eve but we were still unsure as to how it would all unfold. We had many ideas and had even discussed this with many people, not the family though. Since we still had a couple of weeks to decide we continued to think about this so that we would make the right decision.
