Boo I didn't even think of that! I think my partner has one of those that he has used for fishing! Great idea and will make sure he still has it and it's useable... Just incase! Thanks 
Firaffe yes they do, so when I came to have a quick google search, absolutely nothing useful came up! I even read one thread on a website that suggested you make up bottles and store them (which are ok for 24 hours or something) just incase of a powercut! WTH?! I would perhaps only do that in massively stormy weather but even so, a powercut can occur at any time of the year and in any weather, really!
Brummagem - they're also a great idea, thanks!
Good question Firaffe, I did ask my mum at one point when I was actually due but she couldn't really remember, which I'm guessing means I was probably near enough on time give or take a few days? I never asked about my brother but again she hasn't told me any stories that we were really early or really overdue.
My mum is convinced that baby is going to be at least 8 pounds because he is a boy, and my brother was heavier than I was. But I suppose you really can't ever say can you? With that and with labour/birth I suppose it depends on your own health/baby's health which depending on your lifestyle could be completely different to that of your own mum?
I really don't know though and could be entirely wrong so that definitely isn't a scientific answer
