Thank you for your reply @emmarightauthor!
It sounds fun going around in field trips with your kids. But I think you are right, hybrid looks like the more practical one.
What's an ECA?
I agree with you on not pushing a child. I've just listened to Naveen Jain, billionaire philanthropist who plans to mine on the moon, say 'you can lead a horse to water, but you can't make it drink.' So, it is better to develop in kids that thirst for learning.
Yeah, time flies.
Peace!
