Difficult Situation to Announce Pregnancy

Sue
My husband and I are very close to our families. We would like to announce our pregnancy to our family at Christmas while everyone is together. We have a family member that has been struggling to concieve for a long time now. They've kept it under wraps. I want to be sensitive to their struggle but also want to tell family (its convienent and rare that we have everyone together) It was so hard not saying anything at Thanksgiving. Thinking about delaying our announcement and telling family one at a time as to not make a scene or cause pain for them. It also took us a while to concieve and honestly if they concieved before us I would be so incredibly excited for them but it would still hurt. Any suggestions on how we should or should not announce?
