Does buddhism allow for families?

I have studied Buddhism for a few years now, on and off, and this one question has been bugging me for a long time. Please correct me if I am wrong, however, the way that I understand it is that Buddhism is all about the cessation of suffering. In order to end suffering, we first need to end attachment. By being attached to objects, we suffer when something happens to those objects. Instead of connecting and attaching to the objects and perpetuating suffering in our lives, we should instead focus on the here and now and concentrate on existing rather than material things. My question is: **How does buddhism allow for the existence of families?** I cannot think of a more connected and attached system than the familial system. Significant others, children, siblings are all people that we can't help but love and feel attached to. I just can't seem to fathom a family that does not end in suffering when a member dies. Just to be clear, I am searching for an authoritative answer from a legitimate source, not a personal anecdote or opinion.
