Being induced in a week !!

Steffi • Have 3 amazing children. 2yrs-14yrs . X
Just wondered how long it takes to be induced to giving birth when no signs of labour. Last time I was induced was cod waters broke and labour stopped. This time it's because of my age and risk to baby who is big!! I'm so exhausted and feeling sick, driving me nuts 9 days always seems so long!! 😬
I read that induction can still take up to 3 days. I'm wondering how to cope with child care for my other two great children. 
Thanks for your advice x
