Amy-we r having a surprise aswell, we found out with our 1st DD as I was super hoping for a little girl & wanted to get myself excited and mentally ready for a boy if she hadn't been a girl. Then 2nd we had the surprise for DS, don't know why I was so nervous I wouldn't be as excited for a boy cause I just adore him more then I thought I could. DP had trouble bonding with him as he really thought (& hoped) for another little girl & I think was a bit shell shocked so took him a while, while I had bonded with baby growing in me already. The one thing that is swaying me to not find out again is, well I did love that final "it's a ...." & knowing id get to find out if we have a boy/girl helped getting though that last bit of pregnancy !
The one thing I was super nervous about with no 2 was that I couldn't love them as much as I adored DD as I just couldn't imagine that I could love someone as much as I did her as I thought she was just amazing ! But I fell in love with him just as hard & can't wait to do that again !! Sorry that was all a bit mushy !!
Well 2 weeks of work down & I've actually enjoyed it, it's nice to not be mum for the day and spend an entire day having adult conversation ! Plus my brain feel like its getting a bit of exercise again which feels good ! So hasn't been half as bad as I expected and of course it's only till November so not long, plus got my 1st pay check & it's so much better then maternity pay ! 
Had 16week check & heard baby's heartbeat, DP thinks its another boy but I'm feeling like its a girl. I did the bicarbonate test which didnt fizz and when I was pregnant with DS my body hair just stopped growing but it's growing normal like it did with DD & it's my first instinct but who knows !!
I will need to go back to work after this one but will have another year or so off, we r moving home to Australia in March (hopefully) so may take a little longer off, but as we want another 2 after this one, will need to make some money at some stage !
Maths- what a lovely DP u have organising a private scan !
2boys-your midwife didnt sound very helpful, I think they would have better people skills if this kind of job !
Hope everyone is having a nice weekend, I'm making a decadent chocolate cake to take to work tomorrow (stops me eating the whole cake myself !!)
