This is something that worries me. Our parents live abroad and although my mother is planning to come and visit for 3 weeks (including one week before my due date), I don't have a backup plan with regards to childcare for my 3yo DD if the baby comes early.
We have moved to a new area fairly recently and haven't had the chance to get to know the neighbours / other parents (from the local preschool). Our friends all live at least within 1 hour drive, and I can't imagine asking them if it happened in the middle of the day (they would be at work). DD does attend preschool during the day, but it only opens in the morning so they wouldn't be able to cover either.
What did you do with yours? My dh reckons that some people must take their children with them to hospital...???
