Oh, you mean a carry-cot.
A lot of couples prefer not to find out before the birth, they like the anticipation. Also, removes the need for a tacky “reveal” party unless they really have to join the celebrity sycophants 
Most of my younger colleagues also prefer the idea of neutral colour baby clothes so that they can pass them around the family, or keep them for the next child if they plan on having more than one. If you’re slavishly sticking to the “pink for girls, blue for boys” thing, then having one of each means buying two separate sets of baby gear
Even if that’s true, the amount is going to be negligible. I was reading up on it; apparently it involves finding DNA fragments floating around in the mother’s blood (vs inside cells where most DNA is found). Then they sequence the fragments to determine which chromosome they came from. If some came from the Y chromosome, it’s a boy; if not, it’s a girl. To detect trisomy, they look at the proportions of fragments from each chromosome to see if any are overrepresented. All this assumes the mother is chromosomally normal.
Also, AFAIK the reason women are more prone to autoimmune diseases is X-inactivation. In every cell, one or the other X chromosome is inactivated, and immune cells with one X chromosome expressed can sometimes develop antibodies to cells with the other one expressed.
I was talking about microchimerism, which i guess is different from what this test is looking for:

Fetal Microchimerism Microchimerism is the fetus’s cell legacy after pregnancy. Fetal stem cells can leave the fetus and migrate across the placenta to engraft in the maternal bone marrow and other tissues. The transfer of fetal progenitor stem cells begins four or five weeks after fertilization and continues throughout the pregnancy. This form of microchimerism occurs in both male and female embryos, but the detection of male microchimerism in maternal tissue is easier to detect due to the unique presence of Y-chromosome in the women.

I’ve heard ‘crib’ being used in BrE - usually only if it’s an old-fashioned thing, small to the extent that it’s only really suitable for 0-3 months, probably made of wood, maybe with rockers.
Which gizmo an American would call a “'cradle”. Damn, but this multilingual stuff is hard. 
Reading the thread, can I sum it up by saying prospective parents in London say “No sex please, we’re British?”
Unless you’re an aphid.
That’s what they are called, as in, that’s what people call them:
Your note (as well as criticism of all the wildfires they apparently have caused) can be found under the “Criticism” heading.
Yeah, it was weird for my parents to buy us baby stuff at for our baby shower, but my wife wanted one, and having one is her family’s expectation, so obviously it was up to her.
My mom’s love of buying things for my kids eventually won out over any awkwardness, haha.
Isn’t the tiny little crib like thing you use for the first few months a “bassinet”?
Right - cradles rock.
I have a great idea for a gender reveal party. Store bought sheet cake. Blue filling if a boy or pink filling if a girl. And hopefully the cake doesn’t start a wildfire.
When the wind blows…
(We used to use bassinette, but it sounds old-fashioned now. As mentioned up thread, “carry cot” is more likely now).
Damned good question. I was sure till you asked me. IANA parent; the last time I used a bassinet I was the guest of honor sleeping there.
It seems from Googling that in US parlance a bassinet is a small high sided newborn bed. Maybe it sits on the floor on short legs, maybe it sits on a table or clips the side of the parents’ bed.
More Googling suggests that in US parlance a cradle may be larger, and usually has a rocking feature.
Tying my comment back to @Mangetout’s words that triggered mine …
It seems the rockerness suggests a cradle in US parlance but the newborn size suggests bassinet would be the US term.
Babies are hard enough without all this terminology nonsense. gaah!
When i had babies, a very small bed that might have legs or might just be places on something was a bassinet, and a simple bed that was made of wood and had rockers was a cradle. I also had a “car bed”, which could be folded up and carried when visiting friends, but as it had become illegal to actually use them in a car, they were no longer available for sale. (Even though i never used it in a car and found it super helpful.)
The basic small bed that you might put a baby in from when it leaves the parents’ bedroom until it is old enough to use a regular bed is a crib in the US. I think we also use “crib” to describe a thing that holds cattle feed, and maybe other things with a similar shape.
I don’t think I’ve even seen “carry cot” outside this thread.
I don’t recall anyone calling it a bassinette in the UK, but maybe people do
Check
Check (often not much bigger than a bassinet though) often were handmade so size varied and handed down through generations.
Crib, here in the US is the larger baby bed with slats for sides, the mattress adjusting down from the top so a standing toddler couldn’t climb out. Here the the US federal guidelines are:
… Your full-size crib should have interior dimensions between 27 ⅜ - 28 ⅝ inches in width and an interior length between 51 ¾ - 53 inches. With these parameters, a standard crib mattress will fit safely in your crib….[from pottery barn kids]
My new 5 week old grand son has a bassinet next to his parent’s bed and a full size crib in the nursery which he’ll transition to when he no longer needs to nurse several times during the night.
In Scotland you can get a free “baby box”
Yeah, that looks like something different.
And I was wrong about the autoimmune diseases, the increased risk is a result of X-inactivation, but more likely due to RNA-protein-DNA complexes generated in the course of X-chromosome inactivation rather than simply different genes being expressed in different tissues:
They didn’t discover it before because they were using a male cell line as the standard, and the relevant protein is never expressed in males. 
And the above study was funded by the NIH, and is probably exactly the kind of thing Trump is cancelling. 
I’m pretty sure the small baby bed I got, that could be strapped to the side of our bed and the side let down so it was open on the bed side, was called a crib; “Next to me crib” was the biggest brand. My daughter didn’t sleep there for long, though; she ended up in our bed with me.
When she got too big for that we had the choice of getting a standard cot or a ‘cot bed’ that could be transformed into a toddler bed by removing the barred sides. (When we were kids, cots had a drop-side, but that’s illegal now.) My husband bought a cot bed, but she hated the cot so much we gave up, and when we did get her to sleep in her own room, she went straight into the single bed we already owned for guests, with a bed rail to stop her falling out. So both crib and cot were a waste of money.
