We’ve just got home from the 12 week scan and I’m delighted to report that the news was all good: both kids look to be in fine fettle, and the bits that they measure on them to assess the risk of Downs (the thickness of the nuchal fold at the back of the neck, and the length of the nasal bone) indicated a very low risk. The risk is still very low when my advanced age is taken into account, so as far as we’re concerned this is one thing that we will no longer worry about!
It was fabulous to see the babies again. It’s now a bit difficult to get them both in the same scan shot, so from now on I think we’ll be seeing them in separate images for the most part.
Twin B (the ‘top bunk twin’ in the nine week scan picture) was kicking back in a fairly relaxed-looking manner, not really moving much at the start. This made it very easy for the radiologist to get the necessary measurements. Here’s Twin B’s profile:
Twin B also gave us a look at his guns (let’s assume that Twin B is a boy, for ease of reference):
Everything else was looking great – all the bits are in the right place, and functioning properly. Twin B is currently 63.83 mm long from crown to rump.
While Twin B was being measured and checked out, Twin A was squirming around like a little monkey. Once attention shifted to her (again, just using that term for ease of reference), we realised that she was all scrunged up and that there were some baby twin warfare activities underway, with a bit of kicking going on. Luckily, there’s a lot dividing the two of them, so Twin B wasn’t bothered (yet). However, Twin A might want to remember about Twin B’s guns and rein in the kicking later in the pregnancy…
Twin A’s wriggling made it slightly more difficult to get the measurements, but the radiologist managed it in the end. Twin A was measuring at 57.85 mm from crown to rump, but the slightly smaller size is probably just because she was all curled up:
And here are the feet responsible for all that kicking:
We also heard both twins’ heartbeats, which was awesome. And weird. THREE heartbeats inside me right now, people!
Finally, here’s a classic 3D baby shot, making the kids look like tiny aliens:
A lot of people have asked us whether we’re having fraternal or identical twins, so we asked the radiologist whether this is something that can be confirmed at any stage during the pregnancy. The short answer is no, for a pregnancy like this one, anyway: if they were in the same sac they’d definitely be identical, but ours are in separate sacs. We can’t tell how early an egg might have split, though, so it’s possible that they could be identical, but have just developed their own sacs and placentas. We learned this morning that the only surefire way of finding out is by having DNA tests after they’re born (and really, who could be bothered?) Apparently it’s not unheard-of for twins to be declared identical when they’re tiny, only for noticable differences to become apparent as they grow up.
Of course, another surefire way of confirming that they’re fraternal will be if we have a boy and a girl, but we won’t know that for another six or eight weeks. Yes, we’ll definitely find out, and yes, we’ll definitely tell people!
