Phryn thanks for coming back and letting us know, I'm thrilled for you!
Banana What a beautiful scan picture, congratulations! 
To add to the nappy bin debate, we don't have a proper nappy bin but a bin that closes airtight in the nursery and an airtight bin in the kitchen (i.e. the lid clicks shut) and we have no trouble with poo smells at all. I think it's more of a problem with swing lids?
Thanks to whoever asked the question about cot mattresses, I was having the same dilemma! I think I will research some more. DD will be 18 mo. when the new baby arrives so about 21-22 mo. by the time the new baby moves out of the moses basket in our room, so I am undecided about whether to keep her in a cot or move her into a big girls bed, especially since we have a single bed in the spare room already - it feels a bit wasteful throwing it away if we don't need to.
I think my interview went ok today, I won't hear back until Monday though, so I just won't think about it until then.
Told MIL this morning, she was thrilled and not expecting the news at all! I think she spent all day showing people her copy of the scan picture 
Telling my parents tomorrow afternoon, my suspicion is that they already know, but I'm still looking forward to it
