Thanks everyone. I'm lucky in that DH works from home, so will be around anyway. I'm hopeless at asking for (or allowing) help from friends/family but I think that's something I'm just going to have to get over!!

I'm not too worried about missing my DD's 1st birthday. If I have to I'll have it in the hospital - there is no way she's missing out on her first party!! That's provided this little one doesn't decide to share her sister's birthday of course. DH will bring Iz to the hospital with him each day (or however long we stay) for visiting, so I'll get to spend lots of time with her (private room, private hospital), but I'm just worried she'll be confused by having me come and go, so to speak. I still can't get my head around to thinking I will have another baby to think of, not just DD, so I guess until that realisation hits me by way of a little bundle being put into my arms I'll struggle with making this decision for anyone's good other than my DD's - makes all your suggestions of leaving the decision until it has to be made very good ones!!
