Oh roxvox that sounds horrible and very scary - my sickness has come back too but thankfully not in the middle of the night.
I am struggling to keep up with this thread but massive unmumsnetty hugs to everyone having a tough time - hang on in there.
Spark - I think I'd press ahead with the boiler. You may go overdue and the whole thing will be sorted before baby arrives. I agree that the main inconvenience could be hot baths/showers for you.
Pinkforboys - Did you mention that Michael Rosen was visiting your DS's school today? Would be interested to hear how that goes - I have mixed feelings about him. Do you think you'll carry on your PTA duties post- baby?
One of the things I'm going to miss is being able to go in and help regularly at DD's school. It shouldn't make a difference (as lots of parents just aren't in a position to be able to volunteer) but being a known 'face' up at school has definitely had its advantages.
