If you were me and labour kicked off at 11/12pm, would you ring for nan&grandad to come and collect DCs (18m and nearly 4) straight away or come and sit with them incase they wake or wait and see how things progress and ring them once MW has arrived and confirmed baby is imminent? I can't decide what's the best option as I know third time round there can be a few false labours so don't want to get them out unnecessarily.
