blue thanks for that - we thought the catch was a bit stiff, but if that's the only issue, we may well go for it, I think. nature thanks - we do def want the 15% off!
alice and sultana now don't forget, back in the day babies only had a lump of coal and a clip around the ear, and they all turned out fine. 
nature you poor love. Of course you're worried - it's natural. Your DH can help, if you tell him - even if he is already stressed, this is his baby too, and he will not want you to worry alone, I am sure of it. If you keep trying to hold it all in, the worry will magnify itself - I speak from experience! Let it out - to us, to your DH, your Mum, whoever you want. It will help, and you'll get some perspective and start thinking of how to get through the next day and a half, rather than panicking.
As for being a failure - BOLLOCKS. You aren't. That's all I'm going to say about that.
Try to go easy on yourself - who gives a STUFF about work deadlines, cockwomble colleagues (who, by the way is massively precious sounding, and needs to man the fuck up) - this is about you, your DH and your baby. Cry as much as you need to to show them how crap life is for you right now - you deserve support and care, not stress. Don't make life harder for yourself by trying to get through this alone, my love.
Hopefully on Monday you can get all excited again.
