Hi Mamalove
Most hospitals will recommend being induced after 24 - 96 hours following SRM, as there is evidence to suggest that chance of infection is roughly doubled after 96 hours, although still extrememly small, hospital would also recommend IVantibiotics after 24 hours while in labour, and some places seem to give these at home, others will not.
You dont have to do anything you dont feel happy with, but the hospital will start to crank up the pressure to be induced after a certain time, but it is generally considered acceptable to wait for up to but not more than 96 hours, checking temp etc, as recommended in the NICE guidelines, so you would be well within your rights to be quoting the nice guidelines of 96 hours to them.
You will always hear of a story like bublagirls friend, and although it is really sad, it is also very very rare, so please dont be too swayed by that.
The other thing to consider is that if you have to be induced with a second baby, it can still be a very positive experience - you dont have to stuck to a bed etc, although its not exactly a homebirth.
Actually there are loads of other ways it could go, if your waters break you can just go into labour, and about 50% of mums do this within 24 hours. If no sign of infection, you dont have to have the abs, and go in for induction. You might not break your waters first. So try not to worry too much about it at this time.
Good luck
