I know what you mean about the bigger hospital, my hubby was born at Chester so He quite liked the idea of our LO being born there but Warrington is so handy and so far I have had a good experience with them apart from the grumpy lady ha ha, our scanner was called Elizabeth I think so not the same one but at least you know there are a few nice ones.
The roadworks should be done before you are due think they are for 26 weeks so just about timed with your due date ha ha, omg your family does have fast deliveries!!! you can go and camp at mine if you want ha ha!!! I would definately get the car packed before hand. At least it will be over for you quickly and you will have your LO in your arms sooner if you are like your mum and sister so thats a bonus!!!
