Thanks for the question! While from an emotional perspective, I care a ton about our kids' wellbeing, from a utilitarian standpoint this is a relatively minor consideration given I hope to positively impact many beings' lives through my career. Thus, we looked at the child's wellbeing on a very high level - guessing that our children have good chances at a net positive life because they will likely grow up with lots of resources and a good social environment. The one aspect we weren't confident enough to just eyeball was whether lots of nanny would be bad for them, hence we did some research on that (under "Child health").
Thanks for the added perspective!
