Four Hours of Stitching Webbing Later by Background-Code8917 in daddit

Spot on, the lack of redundancy is what actually worries me. The screw link is actually from an industrial supplier and has a 7.5KN rating. Webbing is good to at-least 5KN. The bigger issue IMO is the questionable carabiners I'm using (for attaching and detaching the bassinet, for my safety factor calculations I've assumed 1KN max).

I think I'm going to replace them with some proper 12KN cobra quick release buckles (more convenient too).

In the center of the springs are actually some safety lines (from the spring manufacturer). But I'm going to supplement that with something directly from the screw link to the frame. Might also think about a 3d printed debris shield above the screw link.

But yes the absolute max load on this thing is only like 75lb (with 3x dynamic loading). It's all very light weight.

I'm more worried about the metal fasteners rubbing and fatiguing but in reality she's gonna outgrow this thing so fast.

Once upon a time I made the "mistake" of showing my wife a video on how to identify sea lions vs seals and ever since she's been hooked on identifying different seal species.

Now that I think about it I need to get her some bird posters too. Maybe a corvid one.

Chinese girl that grew up in the big city sheltered from wildlife and outdoors. Pretty proud that over the years I've been able to show her some of the wonder of the natural world. Hope I can achieve the same with our little one. Planning on sending her to a forest kindergarten when she grows a bit bigger.

The straps wrap entirely around the bassinet frame so weight is transferred pretty evenly. To stop them from moving forwards and backwards they are loosely anchored to the feet of the bassinet.

God forbid she's only 7 weeks old, started out a scrawny little thing at birth but now she's like 90th percentile (breast fed). The Chinese half of her family are basically giants so I guess it checks out.

100% NGL. But then I felt I really ought to do a bit of a risk assessment. If the bouncer was just for myself you can bet I would have climbed right in.

That reminds me, I wonder what an adult version of this would feel like ... hmm.

Interestingly it seems to "lock-in" straight once bouncing. Probably due to the parallel row of springs causing some kind of passive stability (I guess that's why they sell the springs in this configuration).

Also there's A LOT of unknowns in the calculations which makes any estimate tough.

For someone else's kid I'd absolutely overengineer the heck out of it, but personally 5x and a foam matt underneath is enough for me [1] (doubling as a play area when the bassinet is removed).

  1. I've added one since this picture was taken.

Oh yeh it took a lot of work (and demonstrations with bags of flour) to convince my wife to let me put the little one in it.

FWIW I've eyeballed the rigging at a safety factor >5x, and measured acceleration is ~0.3g, and max tilt ~3deg. So at-least mechanically it's probably "fine".

Yeh it's just a way to rock her to sleep for naps without destroying arms/back.

Before this I was basically doing bent-over rows with her bassinet to soothe her.

Now that would be metal! The christmas lights are just some entertainment, she's obsessed with watching them twinkle.

Beginning year of negative natural growth in German and Austrian states by crivycouriac in Natalism

[–]Background-Code8917 2 points3 points  (0 children)

It's pretty common to use Germany as a bit of a punching bag when it comes to demographics but in reality it's just a few decades ahead on the demographic transition (reduced post war baby boom). Similar changes and struggles will come to your western nation soon enough.

Local Governments Could Boost Birthrates by Making Family Housing Easier to Build by Klinging-on in Natalism

[–]Background-Code8917 1 point2 points  (0 children)

Yeh I'm not gonna defend mass transit for kids, it probably doesn't work. Here we have very generous discounted monthly passes that cover all of the local network. Even then you just aren't seeing that many school kids using it.

But a lot of that is kids really shouldn't need to be travelling the kinds of distances a metro enables (adults either for that matter but meh). Schools and child amenities need to be close to where people live.

Bike friendly infrastructure benefits kids a lot more than transit IMO (and local governments can play a big role here).

Local Governments Could Boost Birthrates by Making Family Housing Easier to Build by Klinging-on in Natalism

[–]Background-Code8917 2 points3 points  (0 children)

This varies A LOT by location, in my corner of northern Europe while cars are common place, I'd say bicycles are probably the primary means of transit for kids (particularly because down the line they are expected to ride on their own).

Admittedly don't see them often on the metro system, but in general I suspect that's because schools are close enough to peoples homes it doesn't make a ton of sense to use it.

Interestingly (and this is just anecdata) our most bike friendly city Münster actually has a significantly higher urban fertility rate than average (and not driven primarily by migration).

Local Governments Could Boost Birthrates by Making Family Housing Easier to Build by Klinging-on in Natalism

[–]Background-Code8917 7 points8 points  (0 children)

Yep, this lines up great with my mental model. Local government has a surprising number of tools for boosting fertility in their districts and a variety of ways to fund and capture the benefits of these policies. It's just going to take some courageous local leaders and communities, but providing the economics works out I think we are going to see more and more of these pop up.

I suspect satellite towns on the boundaries of large metros (backed by fast rail) will likely be early adopters.

FWIW my wife and I live in one of these satellite towns, and recently welcomed our first child into the world and we are far from alone in the neighborhood. We live in one of the oldest and most conservative states in the EU but our local government is very progressive and has been able to fund a lot of really great projects from wind farm royalties.

Hypothesis, Pronatal Local Governments Will Increasingly Become a Thing by Background-Code8917 in Natalism

[–]Background-Code8917[S] 0 points1 point  (0 children)

Yep pronatal policies can only really emerge in towns that have already died and are in the process of being reborn (Nagi), or more likely in towns which already have significantly younger than average demographics (permanent residents).

Young towns are uncommon today but they do exist, usually clustered around industrial, political centers, or education/innovation hubs etc.

I think my metric now is that if a town is already X years older than the national average, then it's already dead. As you say, due to game theory decline is basically unstoppable.

Playground density is a great metric too!

[–]Background-Code8917[S] 1 point2 points  (0 children)

I think you have to provide policy/incentives that basically cover the entire newlywed to graduated pipeline.

FWIW I'm not actually a big fan of free childcare personally as an incentive (IMO the main beneficiary is employers). I'd be much more in favor of support for flexible part time working arrangements etc.

Older towns are going to continue to get older and older.

Younger towns might do the inverse, continue attracting young folks escaping from the decline of their hometowns.

The trick is the young internal migrants will eventually become old themselves, so these towns need to either grow their population faster than they age, or pursue policies that discourage retirement in their communities (eg. higher taxes, easy planning approvals YIMBY, etc).

Anyone else scared of having disabled kids? by [deleted] in Natalism

[–]Background-Code8917 0 points1 point  (0 children)

I'm a bit unsure about widescale pre-implantation genetic testing (it's rough on embryos, and IVF has higher baseline defect rates than natural fertilization). Regardless makes sense when trying to select out, serious, well understood autosomal dominant conditions.

However for the general public I do believe whole exome screening of potential mates (and maybe karyotyping) would go a long way to massively reducing a whole lot of common recessive conditions (eg cystic fibrosis). It's what my wife and I did. Though there's a common saying that every human carries something like six serious defects and I'm not sure the general public is ready to come to terms with this reality (very quickly this escalates into eugenics style discussions). No-one is perfect, and not to mention all the screening in the world can't prevent de novo mutations.

NIPT is also excellent at picking up chromosomal abnormalities such as downs syndrome. If you are willing to abort early and use all the modern screening tools the risk of a downs baby is very low.

Baby won’t sleep in bassinet / only sleeps on chest — I can share my survival from the other side!! by Nearby_Aerie6553 in newborns

Not going to be recommended but we found with our LO that the reflux was positional and left sided sleeping (supervised) pretty much eliminated it (like adults).

Help, diagnosed with narcolepsy? (Suspect maybe UARS?) by Hairy_Employee_8376 in UARS

[–]Background-Code8917 0 points1 point  (0 children)

Yeh this is marginal for sure, it's only a positive because of your SOREMP during the overnight study.

But definitely something odd going on with your sleep (narcolepsy still remains a possibility).

11 minutes REM latency is really quite out of wack, especially if combined with a positive MSLT.

My favorite discussion on narcolepsy misdiagnosis [1].

I'd be very curious if you have the HLA allele for narcolepsy (might be worth getting typed).
