My wife and I just started 2 months ago (both getting ready for Level IV and V IAF this weekend) and we have 2 kids. We talked about it, and the concession we have made is that we will NOT jump together.
We both understand the risks, and the odds of something happening to both on th same jump, but we figured if we are gonna do this, that that is the responsible thing. One of us will ALWAYS have feet on the ground.
Other than that, the kids LOVE the DZ and all associated with it, and I THINK the folks age getting more comfortabel w/ them.
