Confuddled hope things are easing off today and you're able to rest.
Gummi yippee for heartbeat!
Keep on truckin' with the .ppt, Tramp!
Hurray for painting success Possom. You may have a mini-Rembrandt on your hands there! 
Lexi yippee for you too on the presentation! Well done that girl! Proud of you. (And hope you can avoid any guilt about going back to work!)
Sheldon I second everyone's sensible comments on childcare. I think sometimes people just have to be told that it's fine to have their own opinion but when it's a contentious subject it's sometimes best to express it once and then leave it ? for good. You don't want to have to feel like you need to be on the defensive for the next five years. You could tell her how much you and DH would value and need her support on this, despite her different views, thus giving her the opportunity to be a big person about it. May also be a reasonable and good thing to point out the difference generational and societal differences - e.g. woman having own career and pension etc. And hopefully DH will chip in on how beneficial it is for family as well.
Three I read that book a long time ago - think will revisit it, thanks. I know, I get annoyed when I hear people say stuff along the lines of 'I don't know how you can be parted from baby/toddler for a second'. But, erm, aren't the husbands and partners of SAHMs having to do precisely that to fund their life?! MUCH prefer more of a balance both ways, which is why I'm impressed with DH seriously considering dropping his hours to do more daddying AND to support my need to do more jobbing!
And thanks everyone for the supportive comments on admitting I may have taken on too much for this stage in pregnancy, though! I appreciate it lots 
Our 20-week scan was fine! Took four bloomin' hours in total but worth it! Had a coffee first thing so that they would both wriggle about (two weeks ago one was asleep) and they caused the sonographer a lot of work locating everything! All looks to be in good shape, thankfully. Heads are both up beyond my belly button now (eek!) and their feet are down below. They were prodding and elbowing each other all the time - and we were doing funny 'Oi, gerrof!' voiceovers - hilarious!
