It does seem like it can run in the family but doesn’t always mean it will happen, they say that women who was born early is at a higher risk of also labouring early but as I said doesn’t mean it’s definitely going to happen
It can. Particularly if it’s hormone or cervical incompetency related as there can be genetic precursors for these
