RE childcare:
I met someone who has done this and he was saying how it was actually a great job for introverted people (he was an introvert himself), despite the fact you're working around young kids who are brimming with innocent curiosity. I suppose it is easier than expected as your interaction bears no real judgement or (social) expectations from the children and you just have to make sure you don't act or say anything inappropriate.
Yeah, I've found this to be the case too - I think especially if you're an adaptive/P. I teach, and I generally find the experience quite enjoyable. But having to follow an agenda and be stymied by ambitious expectations which don't match genuinely possible outcomes, and having the time together so narrowly focused in scope rather than incorporating quality-enhancing breadth, can be quite exhausting. I've often wished we could just explore wherever the student wants to go; it's tiring having to continually set them back on task. (Though I will say it helps the P teacher learn and develop.)
When I've done plain babysitting, more or less, it's great. You get to explore with the kids and their energy and curiosity can be really fun for an NTP to experiment with. They're great to test ideas on and letting your silly side/Ne out is *actually part of the job* (how awesome is that?). The lack of an agenda or judgement, as long as you prioritise safety and don't mind kids, is really great for IPs. Liking kids and being interested in people helps, but it's also fun if you're simply not a dick and interested in models of mental development and social dynamics. Most of the time you're simply observing, not interacting, and you start musing about things you've read regarding humans/animals/power/learning, and see them intertwine before your eyes.
Young children are more mentally open and malleable too, so you can seed different useful T patterns/efficiency optimisation techniques and watch for fruit. It's nice to pass on the mental protocols that Ti naturally develops - you have fun leveraging their complexity into a verbal form a 5 year-old can understand and at the same time know you're doing something useful. I think education of some sort is a natural path for INTPs, because the inferior's pull on the dominant (in our case, to socially externalise our internal products) is satisfied in an energy-efficient way. There are plenty of educational moments, and many hilarious ones too.
And of course if you're tired and don't want to do anything, you just make sure the kids don't kill themselves.
I imagine in large groups though it can be much more exhausting, especially if your hands are tied by company regulations and such. Small groups or one-on-one works best, I think.
[Unfortunately I don't think it pays too well... I imagine if you regularly wanted top-tier clients who would provide good money, you'd have to provide a hell of a lot more than simple babysitting. I've had a couple of lucky instances though, and they were fantastic.]
