Two week vacation denied

Is it normal to have a two week vacation denied? I took one last year and was told that was a one time thing. Other juniors (outside of my group) regularly take two weeks off but I was told to limit it to one week since it’s too difficult on the team - this is a bit harder for me to arrange financially as a family with kids (taking 4 one week vacations vs. 2 vacations) and I haven’t heard of this before. Thanks!
