This is great, Jeff and I have been trying to figure this out.

A lot of lessons include learning to float on your back. This makes sense for babies, who are more chub and less bone. It seems like ability to do this for kids and adults depends a lot on how buoyant you are, and my kids are not built for it. One of mine managed to backfloat once under perfect conditions, but I'm assuming any amount of panic / waves / etc would sink her. So I've stopped trying to use "learn to swim" time for this, and they can practice it "water play" time if they want.

Another question is whether to learn a standard method for treading water vs develop your own style. Both Jeff and one of my kids have developed something non-standard that works for them, and with the other kids I'm unsure how much to teach them the more standard method vs "you do you." Some of both, I guess.

I wonder how much early swim lessons are a proxy for parental conscientiousness, awareness of drowning as a risk, and income. The study considered controlling for income and then decided to instead control for "less than high school education vs more than high school education" on the part of the relative answering the questions. :(

There's a difference between who plans to leave their career and who ends up leaving. 

Some paths:
- childcare is more expensive than one partner earns after taxes, and it's cheaper for one parent to stay home.
- managing work / commute / child appointments (especially if they have special needs) / child sickness / childcare is so overwhelming that a parent quits their job to have fewer things to manage. Or they feel they're failing at the combination of work and parenting and must pick one.
- the family is financially secure enough they feel they can do ok on one income, even though they're not at their wits' end. 

Once you start looking at content in this direction, the algorithms will feed you pro-full-time-mom content. Start searching for things like "homeschool preschooler" and I bet you'll get plenty of videos extolling full-time motherhood made by people hoping to become Ballerina Farm.

And "goal factoring" is a technique for figuring out what you actually want and different ways to get there. 

>As a community we produce more way more breastmilk than we can use!
This doesn't really seem right to me; or at least it relies on mothers' volunteer work to pump, sterilize, and store their milk. If you actually need to get rid of extra milk, pumping and dumping is way easier than keeping the milk clean and cold. And if you have an oversupply, pumping a lot is how to continue having an oversupply.

This is sort of like claims that we could produce lots of vegetables if everyone turned their front yard into a miniature farm and spent their spare time doing subsistence agriculture; technically true but not how most people want to spend their time.

Other health claims: breastfeeding slightly reduces risk of breast cancer in the mother and increases chance of colorectal cancer and breast cancer in the child.

We've done the local public school, yes. More thoughts here: https://juliawise.net/school-your-mileage-may-vary/

Generally they're opposed to using toys not as intended. It is kinda dicey given they can't easily see if anyone is at the bottom of the slide, but the worst that happens is someone gets knocked over.
