Help gender reveal .

So I'm about 8 weeks and I figured if I waited until 20 weeks it would be around Christmas time that we know the gender. (Yay easy gender reveal for the family)

My issue is that my brother and SIL are expecting there baby Christmas week.... I'd hate to take the light away from New baby being that they're having a boy.... The 8th boy of all the grandkids. And I know everybody wants a girl but they would be happy regardless ... Id honestly love to have to girl but I would hate to take the light away from my brothers and sister in laws baby especially if it's girl and all the attention would shift to me and my pregnancy when we should be focused on their baby that may or may not be here by Christmas or a little after,. What would you do? Do A Christmas reveal anyways or wait until the holidays are over baby is born than announce?
