Anna has only just started Kindergarten, and so has very limited experience of school. She did a small amount of virtual preschool, because she didn't like that only Lily had calls, but she didn't like that and we stopped.
They really didn't like watching themselves:

Your children are likely enough to be admitted to the kind of institution that commits to meeting 100% of demonstrated financial need, or otherwise has a similar "100% effective tax rate".
You're not be very interested in saving money for your own future use. The CSS Profile suggesting 5%/y for parental assets means that with three kids at 4y each you might be asked for 60% of assets.
Your earnings need to be low enough just before and during college, either because your career has never been highly lucrative or because you are willing to change your line of work for that time period.
Now that we have a third child I'm thinking about this again, and in our particular case I now think we are pretty unlikely to take the direct-work-minimize-income approach:
Use the user's default browser. You leave the app entirely, and switch to the browser. History, logins, autofill, etc work as the user expects.
(Android only) Use a "custom tab". Same as #1, except the app has a bit of control over appearance (bottom toolbar, custom menu, etc). Also some apps [shakes fist] don't respect your default browser, and always use Chrome for the tab.
I mildly prefer #1 over #2, but strongly prefer either to #3. In-app browsers add friction with no benefit, don't respect user choice, make it harder for Firefox etc, and are insecure (more).
If you click on an external link in Facebook for Android, you'll get something like:
