Wow, in't it busy on here! I can't believe there are almost 100 of us, July/August must have been frisk-o-rama ;-)
Finally had the scan last night at 14 weeks - baby was asleep! So a great photo but no waving limbs like DS1. After, DS pointed to the photo and said "owl."
He might be disapponted next April!
tatooed special welcome with your two babies! A friend of mine runs a "twins and more" group at our local children's centre, and was saying they're encouraging mums-to-be to come along too, to get to tips and advice and support before birth, as getting out of the house with two newborns can be a challenge! There may be one near you?
breast pumps, I was given one second hand by a friend, but it did look nearly new, by the time I'd used it for 10 months it had yellowed a bit! So I wouldn't have a problem using 2nd hand one if it was in good nick, and obviously sterilise and wash it thoroughly. I used Avent Philips hand pump and it worked well for me.
buggies oh goodness, it's funny how exciting they are! We were loaned no less than THREE last time but still ended up buying one in the end! Borrowing them helped to find out what we liked/didn't. I got a babystyle oyster with maxi cosi car seat - been pretty good and cheaper than candys etc. My SIL has cityjogger and I think that's brilliant, SO easy to fold and one of the best things is the hood. It reclines without the hood moving, so when it's sunny, baby stays properly shaded unlike lots of prams.
I'm a big fan of second hand, with a few new treats thrown in, but we were also very lucky to have several friends finished who'd having babies and loaned or gave us gear. It's good for the planet too 
toobreathless DS will be 24 months so also wondering about buggy board or double buggy - thinking I'll put DS in buggy and baby in a stretchy sling for the most part, but that won't always work. Oh, I REALLY recommend getting a sling for newborns...
Sorry such a long post - couldn't resist joining all the recent discussions!
