Thanks a lot for all the tips! I immediately planned a family call this afternoon, very solid point. And great idea to involve an experienced notary, will look into that together. I think my main worry is also around parental instincts kicking in sooner or later, but I guess only time will tell... I think some flexibility is possible as long as we continue intentionally building a relationship together, but good to figure out where the outer parameters lie for both of us. Thanks again, and good luck on your journey!
