I found a great article searching through Hacker News the other day - https://news.ycombinator.com/item?id=32497780

Thought you might find it useful.
P.S. I'm working on believing in myself and shamelessly plugging my weekly newsletter for remote working parents everywhere - check it out. https://thursdaydigest.com/
